Explanation:
Let assume that heating process occurs at constant pressure, the phenomenon is modelled by the use of the First Law of Thermodynamics:
The specific enthalpies are:
Liquid-Vapor Mixture:
Saturated Vapor:
The thermal energy per unit mass required to heat the steam is:
Answer:
The shaft work generated per kilogram is
Explanation:
Given:
Temperature K
Initial Pressure MPa
Final pressure MPa
From the table superheated,
and
Work done by shaft is,
But here efficiency is 0.56,
So work generated per kg is,
Work =
Work =
Therefore, the shaft work generated per kilogram is
