At steady-state, an ideal gas enters a cempressor with a mass flow rate of 10.0 [mol/s]. Thei pressure is 1.00 bar and the inlet temperature is 25.0*C. The gas exits at 25.0 bar and 65.0°C. The ideal gas heat capacity is given by: nlet 4. cnm = 3.60 + 0.500 x 10-3T Where T is in [K]. a) Assuming the compressor is adiabatic, calculate the power (in kW) required. b) in the real process, there is a finite amount of heat transfer. If the compressor operates between the same initial state and final state as in Part A, will the actual power required be greater than, equal to, or less than that calculated in Part A? Explain.

Apiston-cylinder with a volume of 0.25 m3 holds 1 kg of air (r 0.287 k/kgk) at a temperature of 100 c. heat transfer to the cylinder causes an isothermal expansion of the piston until the volume triples. how much heat is added to the piston-cylinder?

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.
