Problem $11\mathrm{.}036$E $-$ Steam power plant with an Ideal reheat Rankine cycle

Steam enters the high$-$pressure turbine of a steam power plant that operates on the ideal reheat Rankine

cycle at $700$ psia and $900F$ and leaves as saturated vapor. Steam is then reheated to $800F$ before it

expands to a pressure of $1$ psia. Heat is transferred to the steam in the boiler at a rate of $6{10}^{4}Bt\frac{u}{s}.$

Steam is cooled in the condenser by the cooling water from a nearby river, which enters the condenser

at $45F.$ Use steam tables.

Problem $11\mathrm{.}036$E$.$d $-$ Minimum flow rate of cooling water

Determine the minimum mass flow rate of the cooling water required.

The minimum mass flow rate of the cooling water required is

$lb\frac{m}{s}.$
