For an isentropic flow along a nozzle, at location A, the static temperature and pressure were measured to be 320 K and 5 bar. What will be the static pressure at the location where the static temperature is 500 K? (Given η = 1.4)

For an isentropic flow along a nozzle, at location A, the static temperature and pressure were measured to be 320 K and 5 bar. What will be the static pressure at the location where the static temperature is 500 K? (Given η = 1.4) Correct Answer 23.8 bar

For the isentropic flow, adiabatic relations can be applied (isentropic means reversible as well as adiabatic). Then using P1/P2 = (T1/T2)(η/η-1) P2 = 5 x (500/320)1.4/0.4 ≅23.8 bar.
