Power Generation/Steam Power/Part7

Sir, From steam table we can calculate the Total heat of Superheated steam at corresponding Steam inlet pressure of Turbine and Outlet of turbine. As per example --(1) steam inlet pressure of turbine is 32 kg/cm2, 450 deg. centigrade. steam outlet pressure of turbine is 10 kg/cm2 saturated. (2)steam inlet pressure of turbine is 60 kg/cm2, 450 deg. centigrade. steam outlet pressure of turbine is 10 kg/cm2 saturated.

So now if we calculate heat from Steam Table, difference of Heat of (2) is coming Less than (1). Why this happen ? Power generated is less in (2) even though pressure is high. Than why we should go high pressure.
