Problem Statement

A Rankine cycle, driven by steam as the working fluid, is to be designed to deliver a net power

output of $200$ MW $.$ The cycle features heat rejection to a condenser which operates at your given

design pressure. Heat is generated by the combustion of your given design fuel. The generated heat

is received into the cycle at a boiler which operates at your given design pressure. The Rankine

power cycle comprises steps $($state points$)1-4$ as described below.

Steam, with a maximum specific volume of $0\mathrm{.}75f\frac{t^3}{l}bm,$ enters a $75\%$ efficient isentropic

turbine.

Saturated turbine exhaust enters an isobaric condenser at the stated rejection pressure.

Incompressible liquid water at saturated conditions leaves the condenser and is pumped

$($at $62\%$ isentropic efficiency$)$ to high pressure.

Heat is added to a boiler to generate superheated steam isobarically.

Given the above information, please determine the circulation rate of steam in the power plant

$(lb\frac{m}{h}r),$ the required cooling water flow rate $($ gpm
