A simple Brayton cycle using air as the working fluid has a pressure ratio of 10.9. The minimum and maximum temperatures in the cycle are 280 K and 1410 K. Assuming constant specific heats, an efficiency of 100% for compressor and turbine, Determine:

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

During a steady flow process, the change of energy with respect to time is zero. a)- true b)- false
