SUMMARY
The change in specific enthalpy for saturated water vapor compressing from 100 bar to 150 bar at constant temperature can be calculated using the enthalpy values from steam tables. The initial approach using the equation delta h = delta e + p * delta v was incorrect due to miscalculating delta e and delta v. The correct method involves directly finding the enthalpy values at both pressures and taking their difference, resulting in a change of specific enthalpy of 190049 kJ/kg.
