A 4cylinder racing engine capacity 2.495liters has a bore of 94mm and a compression ration 12/1 when tested against a dynamometer with a torque arm of 0.461m. A maximum load of 622N was obtained at 5000rpm, and at the peak speed of 6750 rpm, thebload was 547N the minimum fiel consumption was 17.2mililitre/s at a speed of 5000rpm. the specific gravity of the fuel bieng 0.735 and Cv=44200Kj/kg. calvulate the maximum Brake mean effective pressure

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

An air conditioning system consist of a 5 cm diameter pipe, operating at a pressure of 200 kpa. the air initially enters the pipe at 15°c with a velocity of 20 m/s and relative humidity of 80%. if the heat supply throughout the process is 960 w, determine the relative humidity and the temperature at the outlet

Atmospheric air has a temperature (dry bulb) of 80° f and a wet bulb temperature of 60° f when the barometric pressure is 14.696 psia. determine the specific humidity, grains/lb dry air. a. 11.4 c. 55.8 d. 22.5 b. 44.1
