PROBLEM $2$:

Consider the two stages turbine system shown in the below figure and the

input data in the table

$1234$

Steam Sat. vapor

P$1=40$ bar P$2=20$ bar P$3=20$ bar P$4=0\mathrm{.}6$ bar

T$1=500$ oC T$2=400$ oC T$3=500$ oC

$($AV$)1=90$ m$3/$min

Ignoring kinetic and potential energies and assuming steady$-$state

operation determine

a$)$ the total power generated by the two turbines in kW

b$)$ rate of heat transfer dQ$/$dt in the reheater in kW

TURBINE $1$ TURBINE $2$

REHEATER
