Question: 6 . A gas expands through a nozzle from a pressure of 3 0 0 psia to a pressure of 5 psia. The enthalpy change

6. A gas expands through a nozzle from a pressure of 300 psia to a pressure of 5 psia. The enthalpy change involved, \(\mathrm{h}1-\mathrm{h}2\), is \(150\mathrm{Btu}/\mathrm{lbm}\). If the expansion is adiabatic but with frictional effects and the inlet gas speed is negligibly small, determine the exit gas velocity.
