An ideal gas at 15 lbf/in2 , 77°F flows horizontally at 516 ft/s into an adiabatic diffuser. It exits at 28 ft/s. Assume the heat capacity of the gas is constant. a. Determine the change in specific enthalpy (in Btu/lbm) and the outlet temperature if the gas is He. b. Repeat for R-125.
Heat Exchangers
Heat exchangers are the types of equipment that are primarily employed to transfer the thermal energy from one fluid to another, provided that one of the fluids should be at a higher thermal energy content than the other fluid.
Heat Exchanger
The heat exchanger is a combination of two words ''Heat'' and ''Exchanger''. It is a mechanical device that is used to exchange heat energy between two fluids.

a. Determine the change in specific enthalpy (in Btu/lbm) and the
outlet temperature if the gas is He.
b. Repeat for R-125.
c. Repeat for ozone (O3), which has a Molecular Mass of 47.9982
and a Cv0 of 0.1538 Btu/(lbm∙°R).
