An industrial steam cleaner draws water at 25 C and 1 atm at a rate of 1 g/sec through a 1 cm diameter pipe,
pressurizes it with a pump drawing 1 kW of power, and heats it with a resistive heater. The resulting flow is saturated

major application area of thermodynamics is refrigeration, which is the transfer of heat from a lower temperature region to a higher temperature one. Devices that produce refrigeration are called refrigerators, and the cycl
THERMODYNAMIC PROPERTY RELATIONS
n the preceding chapters we made extensive use of the property tables. We tend to take the property tables for granted, but thermodynamic laws and principles are of little use to engineers without them. In this
