Air enters a turbine operating at steady state at 8 bar, 1400 k and expands to 0.8 bar. the turbine is well insulated, and kinetic and potential energy effects can be neglected. assuming ideal gas behavior for the air, what is the maximum theoretical work that could be developed by the turbine in kj per kg of air flow?

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

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

An air compression refrigeration system is to have an air pressure of 100 psia in the brine tank and an allowable air temperature increase of 60°f for standard vapor compression cycle temperatures of 77 f entering the expansion cylinder and 14 f entering the compression cylinder, calculate the coefficient of performance a. 2.5 b 3.3 c. 4.0 d. 5.0
