Question

Air enters a compressor operating at steady state at 15.4 lbf/in^2, 80°F with a volumetric flow rate of 424 ft^3/min and exits at 176.4 lbf/in^2, 260°F. Heat transfer occurs at a rate of 6800 Btu/h from the compressor to its surroundings. Assuming the ideal gas model for air and neglecting kinetic and potential energy effects, determine the power input, in hp.

4.58 Air enters a compressor operating at
steady state with a pressure of 14.7 lbf/in^2, a temperature of 808
F, and a volumetric flow rate of 18 ft /s. The air exits the
compressor at a pressure of 90 lbf/in^2 Heat transfer from the
compressor to its surroundings occurs at a rate of 9.7 Btu per lb
of air flowing. The compressor power input is 90 hp. Neglecting
kinetic and potential energy effects and modeling air as an ideal
gas,...

Saturated water vapor at 300°F enters a compressor operating at
steady state with a mass flow rate of 5 lb/s and is compressed
adiabatically to 550 lbf/in.2
If the power input is 2150 hp, determine for the compressor:
(a) the percent isentropic compressor efficiency and
(b) the rate of entropy production, in hp/°R.
Ignore kinetic and potential energy effects.

Water enters an insulated compressor at a volumetric flowrate of
600 ft3 /min. It enters as a saturated vapor at 30 psi, and exits
at 200 psi and 700 oF. Assuming an irreversible process while
neglecting kinetic and potential energy effects, determine: (40

Air at 95°F, 1 atm, and 10% relative humidity enters an
evaporative cooler operating at steady state. The volumetric flow
rate of the incoming air is 1765 ft3/min. Liquid water
at 68°F enters the cooler and fully evaporates. Moist air exits the
cooler at 70°F, 1 atm. There is no significant heat transfer
between the device and its surroundings and kinetic and potential
energy effects can be neglected.

air)/min....

Air enters the compressor of a simple gas turbine at
p1 = 14 lbf/in2, T1 = 520°R. The
isentropic efficiencies of the compressor and turbine are 83 and
87%, respectively. The compressor pressure ratio is 16 and the
temperature at the turbine inlet is 2500°R. The volumetric flow
rate of the air entering the compressor is 9000 ft3/min.
Use an air-standard analysis.

A) Determine the net power developed, in Btu/h. (Already did
this part,...

Saturated steam at 300 ° F enters an adiabatic compressor with a
mass flow of 5 lb / s. The outlet pressure is 800 lbf / in2. If the
input power of this device is 2150 hp, determine the entropy
generation rate in hp / ° R.

Moist air at 30 °C and 50% relative humidity enters a
dehumidifier operating at steady state with a mass flow rate of
319.35 kg/min. The moist air passes over a cooling coil and water
vapor condenses. Condensate (condensed water) exits at 10 °C.
Saturated moist air exits in a separate stream at the same

A two-part compressor operates with steady state conditions. The
exit of the first part of the compressor is also the inlet of the
second part of the compressor. In the first part of the compressor,
air is compressed from 1.5 bar, 350 K to 5.5 bar with a mass flow
rate of 7.2 kg/sec. In the second part of the compressor, air is
compressed from 5.5 bar to 9.5 bar with a mass flow rate of 5.8
kg/sec. Each unit...
