Question 52
MENAT2 marksNeeds review
A thermal power plant is running with no heat regeneration. The specific enthalpy and specific entropy of steam at the turbine inlet are 3344 kJ kg
and 6.5 kJ kg
K
, respectively. The turbine isentropic efficiency is 0.9, and the mass flow rate of steam at the turbine inlet is 102 kg s
. The turbine power output is __________ MW (rounded off to 1 decimal place).Properties of saturated liquid and saturated vapor at turbine exit pressure
Saturated liquid water: Specific enthalpy (kJ kg ) | Saturated liquid water: Specific entropy (kJ kg K ) | Saturated water vapor: Specific enthalpy (kJ kg ) | Saturated water vapor: Specific entropy (kJ kg K ) |
|---|---|---|---|
341 | 1.1 | 2645 | 7.6 |
