## Homework Statement

An electric generating station is designed to have an electric output power of 1.4 MW using a turbine with two-thirds efficiency of a Carnot engine. The Exhaust energy is transferred by heat to a cooling tower at 110°C.

a) Find the rate at which the station exhausts energy by heat as a function of the fuel combustion temperature Th

## Homework Equations

e= w/Qh=1-Qc/Qh , e_carnot=1-Tc/Th, P=W/t

## The Attempt at a Solution

The only thing i have been able to figure out so far is e=(2/3)(1-(Tc/Th) Where Tc=383K

I have been struggling with this one for quite some time and humbly asking for your help

The book lists the answer as Qc/Δt=1.4((.5Th+383)/(Th-383))

I am so confused...
