![QUESTION 2
Consider a steam power plant that operates on a simple ideal Rankine cycle and has a net power output of 20MW. Steam
enters the turbine at 7MPA and 470.49°C and is cooled in the condenser at a pressure of 10kPa by running cooling water
from a lake through the tubes of the condenser at a rate of 1750kg/s.
Determine the value of entropy of steam at the entry to the steam turbine (accurate to 4 decimal places, using the relevant
equations) assuming that the cp of superheated steam is 2.9503k/kg.K.
HINT: Please donot use superheated steam table for enthalopy and entropy of superheated steam, instead use the relevant
equations since Co is given.
Type in the unit next to the answer. For writing unit, please use the format xX.yy/Mm.ss.
