An ideal gas is flowing at steadystate through a wellinsulat

An ideal gas is flowing at steady-state through a well-insulated throttling valve. The inlet temperature is 491 K and the pressure is 2.32 MPa. At the outlet, the pressure is 6.0 × 102 kPa. Find the outlet temperature.

Solution

for throttling condition,

Final enthalpy =intial enthalpy

hi=hf

cpT1=cpT2

T1=T2

given T1=491=T2

T2=424.13F
