Question

A steam turbine takes in steam at a temperature of 400 Celsius and releases steam to the condenser at a temperature of 120 Celsius. If the turbine takes 500 kJ of heat in each cycle, what is the maximum amount of work that could be generated by the turbine in each cycle

Answer 1

`W= 208 KJ`

Step-by-step explanation:

From the question we are told that:

Take in Temperature
`T_1=400C=>673K`

Take Out Temperature
`T_2=120+>393K`

Heat
`Q=500kJ`

Generally the equation for Carnot Engine Efficiency is mathematically given by

`n_c=(T_1-T_2)/(T_1)`

`n_c=(673-393)/(673)`

`n_c=0.4`

Where

`n_c=(W)/(Q)`

`W = Q*n_c`

`W= 500 * 0.4`

`W= 208 KJ`
