Water at 3.5 MPa and 400 K enters the steam generating unit of a power plant and leaves the unit as steam at 3.5 MPa and 1000 K. The water mass flow rate is 3.5 kg/s. Starting with the full expression for steady-state, steady flow conservation of energy, apply any assumptions and simplify. Clearly state your assumptions. Using this expression, determine the capacity of the steam-generating unit in MW.
