What is the formulae for steam power generation?

The formula for steam power generation primarily involves the Rankine cycle, which can be represented as:

[ \text{Efficiency} (\eta) = \frac{W}{Q_{in}} = \frac{(h_1 - h_4)}{(h_1 - h_2)} ]

where (W) is the work output, (Q_{in}) is the heat input, and (h_1), (h_2), (h_3), and (h_4) are the specific enthalpies at various points in the cycle (boiler, turbine, condenser, and pump). The overall efficiency can be improved by optimizing each component and minimizing heat losses.
