See AnswerQ: Refrigerant-134a enters the compressor of a refrigeration system as saturated
Refrigerant-134a enters the compressor of a refrigeration system as saturated vapor at 0.14 MPa and leaves as superheated vapor at 0.8 MPa and 60°C at a rate of 0.06 kg/s. Determine the rates of energ...
See AnswerQ: Steam is leaving a pressure cooker whose operating pressure is 20 psia
Steam is leaving a pressure cooker whose operating pressure is 20 psia. It is observed that the amount of liquid in the cooker has decreased by 0.6 gal in 45 minutes after the steady operating conditi...

See AnswerQ: A diffuser is an adiabatic device that decreases the kinetic energy of
A diffuser is an adiabatic device that decreases the kinetic energy of the fluid by slowing it down. What happens to this lost kinetic energy?
See AnswerQ: The kinetic energy of a fluid increases as it is accelerated in
The kinetic energy of a fluid increases as it is accelerated in an adiabatic nozzle. Where does this energy come from?
See AnswerQ: Blood pressure is usually measured by wrapping a closed air-filled
Blood pressure is usually measured by wrapping a closed air-filled jacket equipped with a pressure gage around the upper arm of a person at the level of the heart. Using a mercury manometer and a stet...
See AnswerQ: The stators in a gas turbine are designed to increase the kinetic
The stators in a gas turbine are designed to increase the kinetic energy of the gas passing through them adiabatically. Air enters a set of these nozzles at 300 psia and 700°F with a velocity of 80 ft...
See AnswerQ: The diffuser in a jet engine is designed to decrease the kinetic
The diffuser in a jet engine is designed to decrease the kinetic energy of the air entering the engine compressor without any work or heat interactions. Calculate the velocity at the exit of a diffuse...
