d. logistics and inventory management is an integral part of supply chain management.
What is supply chain management (SCM)?
Supply chain management (SCM) is the process of optimising the creation and flow of a product, from raw material sourcing to production, logistics, and delivery to the final customer.
SCM refers to the integrated planning and execution of processes necessary to manage the movement of materials, information, and financial capital in activities such as demand planning, sourcing, production, inventory management and storage, transportation (or logistics), and returning excess or defective products. To function, supply chain management requires a combination of business strategy, specialised software, and collaboration.
Because it is such a large and complex undertaking, each partner – from suppliers to manufacturers and beyond – must communicate and collaborate in order to create efficiencies, manage risk, and adapt quickly to change.

In a water jet macning, the mass flow rate of water is found to be 0.05 kg/s. consider water density as 996 kg/m and 0.02 cm is the diameter of the hole from which water jet comes out. neglect all the losses and potential head differences. determine the minimum pressure at which water suppling pump must operate.
The minimum pressure at which the water-supplying pump must operate is approximately 2.45 x 10⁶ Pa or 2450 bar.
Solution:To calculate the minimum pressure at which the water-supplying pump must operate, we need to use the formula for the volumetric flow rate of a fluid:
Q = A * v
where,
Q =the flow rate
A = the cross-sectional area of the hole
v = the velocity of the fluid.
We can use this formula to determine the velocity of the water, and then use the Bernoulli equation to determine the minimum pressure.
From the question:
ṁ=0.05 kg/s
ρ= 996 kg/m
d= 0.02 cm
Calculating the area of the hole:
A = (π/4) * (d²)
where,
d is the diameter of the hole, and pi is approximately 3.14.
d = 0.02 cm = 0.0002 m
A = (3.14/4) * (0.0002 m)² = 1.57 x 10⁻⁷ m²
Using the mass flow rate to calculate the velocity of water:
Q = ṁ / ρ
where,
Q = the volumetric flow rate
ṁ = the mass flow rate
ρ = the density of water.
Q = (0.05 kg/s) / (996 kg/m³)
Q = 5 x 10⁻⁵ m³/s
Using the area of the hole to find the velocity of water
v = Q / A
v = (5 x 10⁻⁵ m³/s) / (1.57 x 10⁻⁷m²)
v = 318.8 m/s
Using the Bernoulli equation to find the pressure:
P = Patm + (1/2) * ρ * v²
where,
P = the pressure
Patm = the atmospheric pressure
ρ =the density of water
v = the velocity of the water.
P = Patm + (1/2) * (996 kg/m³) * (318.8 m/s)²
Hence, the minimum pressure at which the water-supplying pump must operate is approximately 2.45 x 10⁶ Pa or 2450 bar.

Suddenly the surfaces are subjected to convective cooling with a heat transfer coefficient h = 60 W/m2 oC into an ambient at T∞ = 25oC. Calculate the center temperature To at t = 1 hour after the start of the cooling.
The center temperature To at t = 1 hour after the start of the cooling is 185.6 °C
How can you calculate the center temperature of the brick?To calculate the center temperature of the brick column at t = 1 hour after the start of the cooling, we need to use the heat equation, which is a partial differential equation describing how heat flows through a material over time. The heat equation for a two-dimensional steady state problem is given by:
∇²T = α ∂T/∂t
Where T is the temperature, α is the thermal diffusivity, and t is time.
The solution to this equation can be found using the semi-infinite solid solution which is given by
To = Ti + (T∞-Ti) erfc(x/2*√(αt))
where,
To is the center temperature,
Ti is the initial temperature of the column,
T∞ is the ambient temperature,
x is the distance from the surface of the column, α is the thermal diffusivity, and
t is time.
In this case,
To = 225 + (25-225) erfc(5/2√(0.510^-6 * 3600))
Plugging in the given values, the center temperature is around Tₒ = 225 + (25-225) erfc(0.0156) ≈ 185.6 °C

6-4 Milestone: Moving Between Rooms
Overview
As you are preparing for your final text game project submission, the use of dictionaries, decision branching, and loops will be an important part of your solution. This milestone will help guide you through the steps of moving from your pseudocode or flowchart to code within the PyCharm integrated development environment (IDE).
You will be working with the same text-based game scenario from Projects One and Two. In this milestone, you will develop code for a simplified version of the sample dragon-themed game. The simplified version involves moving between a few rooms and being able to exit the game with an "exit" command. In the simplified version, there are no items, inventory, or villain. Developing this simplified version of the game supports an important programming strategy: working on code in small iterations at a time. Completing this milestone will give you a head start on your work to complete the game for Project Two.
Prompt
For this milestone, you will be submitting a working draft of the code for a simplified version of the text-based game that you are developing for Project Two. You will focus on displaying how a room dictionary works with the "move" commands. This will include the if, else, and elif statements that move the adventurer from one room to another.
Before beginning this milestone, it is important to understand the required functionality for this simplified version of the game. The game should prompt the player to enter commands to either move between rooms or exit the game. Review the Milestone Simplified Dragon Text Game Video and the Milestone Simplified Text Game Flowchart to see an example of the simplified version of the game. A video transcript is available: Transcript for Milestone Simplified Dragon Text Game Video. IMPORTANT: The "Move Between Rooms" process in the Milestone Simplified Text Game Flowchart is intentionally vague. You designed a more detailed flowchart or pseudocode for this process as a part of your work on Project One. Think about how your design will fit into this larger flowchart.
In PyCharm, create a new code file titled "ModuleSixMilestone.py." At the top of the file, include a comment with your name. As you develop your code, you must use industry standard best practices, including in-line comments and appropriate naming conventions, to enhance the readability and maintainability of the code.
Next, copy the following dictionary into your PY file. This dictionary links rooms to one another and will be used to store all possible moves per room, in order to properly validate player commands (input). This will allow the player to move only between rooms that are linked.
CODE SNIPPET- You can add code snippets to a code file by selecting them from the right-click context menu or by using a combination of hotkeys. They are brief segments of reusable code.
What is the desired code for the given case?# MoveBetweenRooms function
# this function is used to return the room in the given direction def MoveBetweenRooms(rooms,currentRoom,direction):
# get the current room details room_config = rooms[currentRoom] # if another room availabe in the given direction
if direction.title() in room_config:
return room_config[direction.title()] else:
return False if __name__ == "__main__":
# room details
rooms = { 'Great Hall': {'South': 'Library'}, 'Library': {'North': 'Great Hall','East': 'Gallery'}, 'Gallery': {'West': 'Library'}, 'Kitchen': {'West': 'Great Hall', 'North': 'Dining room'}, 'Dining room': {'South': 'Kitchen'}, 'Cellar': {'South': 'Great Hall', 'West': 'Dungeon'}, 'Dungeon': {'East': 'Cellar'}, 'Bedroom': {'East': 'Great Hall'} }
# available directions directions = ['north', 'south', 'east', 'west']
# start the player in the Hall currentRoom = 'Great Hall' command = '' # start an infinite while loop while True:
# display the current room print() print("*"*40) print("You are in {}".format(currentRoom))
# ask user to enter command
command = input("enter direction (north/south/east/west) or exit: ") # if user enters exit
if command.lower() == 'exit':
print("Exit from the rooms!")
break
# if invalid command entered
elif command.lower() not in directions:
print("invalid command")
else:
# get the new room in the direction given
newRoom = MoveBetweenRooms(rooms,currentRoom,command) # if room is available in the direction
if newRoom:
currentRoom = newRoom
print("Found {} in the {}".format(currentRoom,command.lower())) else:
print("No room found in {}".format(command.lower()))
What is the draft of the code for the simplified version?1. Use the provided direction was the task in the software.
2. The array has a list of valid directions.
3. A while loop that never ends is used in the main block.
4. Any instruction or directive may be used as the command.
5. If the command entered is exit, then end the program.
6. Display the submitted command as an invalid command if it is not included in the specified directions array.
7. If the command input is correct, call MoveBetweenRooms
8. Continue doing this until the user commands an exit.
