Give me the exact solution for this problem or else down vote.

The exhaust gases from a gas turbine are used as the energy source for a two

stage steam power plant as shown below. The exhaust gases, with an average $Cp=0\mathrm{.}252$

$BT\frac{U}{l}bm-R$ and $MW=29lb\frac{m}{l}$bmol enter the heat exchanger at a temperature of $1036$

F $,$ a pressure of $14\mathrm{.}9$ psia $,$ and a flow rate of $3100lb\frac{m}{sec}.$ The mass flow rate of steam is

$289lb\frac{m}{sec}$ through the high$-$pressure turbine, and $340lb\frac{m}{sec}$ through the low$-$pressure

turbine, respectively. Other known values are summarized in the table below:

a$.$ Determine the temperature $(F)$ of the exhaust gases at State B

b$.$ Determine the volumetric flow rate $($cfm$)$ of the exhaust gases at State A

c$.$ Determine the power $(hp)$ required to drive the two pumps
