Question: Hydrogen (R ) = ( 4.124) flows isentropicallyin a nozzle from initial pressure of 500kPa , with negligible velocity, to a final pressure of 100kPa

Hydrogen

(R

)

=

(

4.124)

flows isentropicallyin a nozzle from initial pressure of

500kPa

, with negligible velocity, to a final pressure of

100kPa

. Because the pressure falls during its journey through the nozzle, this flow is called an expansion. The initial gas temperature is

500K

. Assume steady flow, with hydrogen behaving as a perfect gas with constant specific heats

cp=14.5

. Determine the final velocity of the gas.

Hydrogen (R=4.124) flows isentropicallyin a nozzle from initial pressure of 500kPa, with negligible velocity, to a final pressure of 100kPa.
