Calculate the enthalpies of steam at the inlet and at exit of steam turbine. Also, determine dryness fraction at the exit of steam turbine for Faisalabad Steam Turbine power plant, Having the following data:

ẇ_net = net work output = 66 MW, P₁ = 80 bar, t₁ = 500 ^oC, P₂ = 0.05 bar

Also, find out the mass flow rate of steam and the mass flow rate of cooling water when the temperature difference is 10 ^oC
