Solved: Steam flows steadily through a turbine at a rate
Chapter 5, Problem 549E(choose chapter or problem)
Steam flows steadily through a turbine at a rate of 45,000 lbm/h, entering at 1000 psia and 9008F and leaving at 5 psia as saturated vapor. If the power generated by the turbine is 4 MW, determine the rate of heat loss from the steam.

QUESTION:
Steam flows steadily through a turbine at a rate of 45,000 lbm/h, entering at 1000 psia and 9008F and leaving at 5 psia as saturated vapor. If the power generated by the turbine is 4 MW, determine the rate of heat loss from the steam.
ANSWER:Step 1 of 4
Steam expands in a turbine. The rate of heat loss from the steam for a power output of is to be determined.
Assumptions are
1. This is a steady-flow process since there is no change with time.
2. Kinetic and potential energy changes are negligible.
