An engine manufacturer wants to develop a gasoline engine that produces 300 hP at 6000 rpm. They can achieve 10 bar BMEP at peak power with a naturally aspirated engine, and 20bar BMEP with a turbocharged engine. Most modern light-duty engines have displacements of ~0.5L per cylinder. Determine the displacement and minimum number of cylinders (rounded to nearest whole number) required to meet these specs for: a. A naturally aspirated engine. b. A turbocharged engine.

A test of a drivers perception/reaction time was conducted on a special test track in a rural area. The friction factor f = 0.6. The drivers initial speed is 55 MPH. The track is on level ground. a) When a driver is not texting on his smart phone, a stop can be made just in time to avoid hitting an unexpected object that is first visible 520 feet ahead. b) When a driver is texting on his smart phone, but with all other conditions exactly the same, the driver is distracted and fails to stop and hits the object at a speed of 35 MPH. Determine the drivers perception/reaction time for both situations, for (a) and for (b).

6. Dr. Li boils water using a kettle with a 1.5 kW Nichrome (80% Ni and 20% Cr) heating element (resister heater). The diameter and length of this heating element is 8 mm and 20 cm, respectively. When exposed to liquid water, the convection heat transfer between water and heating element is 800 W m2K . Please find: (25 Points) (1) The surface temperature and maximum temperature of the heating element when water is boiling in the kettle in Dr. Lis office, ESB 751. (2) The surface temperature and maximum temperature when all liquid water has been evaporated and the heating element is exposed completely to the superheated vapor. You can assume the convection heat transfer between superheated water vapor and heating element is 24 W m2K . You can assume the temperature of the superheated water vapor is 100 C. (3) Please justify if the heating element can survive in case (2) without melting.
