Agasoline engine has a volumetric compression ratio of 10 and before compression has air at 290 k, 85 kpa in the cylinder. the combustion peak pressure is 600o kpa. assume cold air properties. what is the highest temperature in the cycle? find the temperature at the beginning of the exhaust (heat rejection) and the overall cycle efficiency.

The y form of iron is known as: a) ferrite b) cementite c) perlite d) austenite

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.

Fluids at rest possess no flow energy. a)- true b)- false
