Dry saturated
steam at a pressure of 8 bar enters a convergent nozzle. The index of
isentropic expansion for dry saturated steam is 1.135. For maximum mass flow
rate to occur through the nozzle, the exit pressure should be
5.32 bar
3.62 bar
4.62 bar
2.32 bar
4.62 bar
Given :
Index of
isentropic expansion, n = 1.135
The ratio between the exit pressure and inlet pressure for maximum mass flow rate in a nozzle is given by,
Hence, the
correct option is (C).
