An engineer has proposed that a simple ideal Rankine cycle that uses refrigerant-134a be used to produce work with heat from a low-temperature thermal energy reservoir. The boiler operates at 1.6 MPa, the condenser at 0.5 MPa, and the turbine inlet at 80 ºC.
(a) Draw a schematic of the ideal Rankine cycle and the corresponding T- s diagram.
(b) Determine the R-134a mass flow rate needed for this cycle to produce 750 kW of power.
(c) Determine the thermal efficiency of the cycle.
a rigid tank contains 20 lbm of air at 20 psia and 70degf. more air is added to thenbsptank until the pressure and
Air at 90 kpa and -7 C enters an adiabatic diffuser steadily with a velocity of 180 m/s and leaves with a low velocity at a pressure of 100 kpa. The exit area of the diffuser is 5 times the inlet area. Determine (a) the exit temperature and (b) th..
