Ответ:
Rate of heat transfer will be 10.69 kw
Explanation:
We have given temperature![T=40^{\circ}C](/tpl/images/0513/4113/ae281.png)
From standard table enthalpy of vaporization 2382.75 KJ/kg
Steam is coming out from turbine at rate of 16.154 kg/hour
We have to calculate the rate of heat transfer
Heat transfer is equal to![Q=mass\times enthalpy\ of \ vaporization](/tpl/images/0513/4113/2b223.png)
So rate of heat transfer![=16.154\times 2382.75=38490.94KJ/hr](/tpl/images/0513/4113/39534.png)
=![=16.154\times 2382.75=38490.94\times \frac{1}{3600}watt=10.691kwatt](/tpl/images/0513/4113/b4716.png)
So rate of heat transfer will be 10.69 kw
