Hey Guys,(adsbygoogle = window.adsbygoogle || []).push({});

I'm trying to solve the problem below:

Steam enters a turbine with a velocity 120 m/s at 600°C and 600kPa. The steam leaves the turbine as saturated vapor at 200 kPa with a velocity of 180 m/s. Heat is transferred from the turbine to the surroundings in the amount of 30 kJ for every kilogram of steam flowing through the turbine. The mass flow rate of steam through the turbine is 20 kg/s (1 kJ/kg = 1000 m2/s2)

Find the work and power.

I'm given the T, v, p initial and p, v final. I think I need to find T final to solve the problem.

How do I go about finding T final? Also, I don't know whether to assume the system is isentropic or adiabatic. Can someone help me on this?
