A heat engine has three quarters the thermal efficiency of a carnot engine operating between temperatures of 65°C and 435°C if the heat engine absorbs heat at a rate of 44.0 kW, at what rate is heat exhausted?

The value is  

Explanation:

From the question we are told that

   The efficiency of the carnot engine is  

    The efficiency of a heat engine is

    The operating temperatures of the carnot engine is    to  

    The rate at which the heat engine absorbs energy is  

Generally the efficiency of the carnot engine is mathematically represented as

=>      

=>      

Generally the efficiency of the heat engine is

=>        

Generally the efficiency of the heat engine is also mathematically represented as

Here W is the work done which is mathematically represented as

Here  is the heat exhausted

So

=>    

=>  

okay i have so many questions. but the big one here is: um wt..f is this mess? ?
