Consider a 50-MW Rankine-cycle steam power plant. The steam enters the turbine at l000 F and 1200 psia and leaves at 1 psia with a quality of 0.90. Water leaves the condenser at 80 F and 1 psia. The power supplied to the pump may be neglected. Determine the thermal efficiency for the power plant and the mass flow rate (Mlbm/hr) of steam in the boiler.

Mechanisms of heat transfer

Heat transfer is an essential discipline in thermal engineering that deals with the transfer, conversion, usability, and creation of heat or thermal energy. Transfer of heat occurs through various mechanisms like conduction, convection, radiation, and change of phases. All these mechanisms have distinct characteristics, but these mechanisms can simultaneously occur in an identical system.
