In a steam power plant 1.5 kg of water per second is supplied to the boiler. The enthalpy and velocity of the water entering into the boiler are 800 kJkg-1 and 10 ms-1. Heat at the rate of 2200 kJkg-1 of water is supplied to the water. The steam, after passing through the turbine, comes out with a velocity of 50 ms-1 and enthalpy of 2520 kJkg-1. The boiler input is 5 m above the turbine exit. The heat loss from the boiler is 1800 kJmin-1 and from the turbine 600 kJmin-1. Determine the power capacity of the turbine, considering the boiler and turbine as a single unit.

Question
In a steam power plant 1.5 kg of water per second is supplied to the boiler. The enthalpy and
velocity of the water entering into the boiler are 800 kJkg-1 and 10 ms-1. Heat at the rate of
2200 kJkg-1 of water is supplied to the water. The steam, after passing through the turbine,
comes out with a velocity of 50 ms-1 and enthalpy of 2520 kJkg-1. The boiler input is 5 m above
the turbine exit. The heat loss from the boiler is 1800 kJmin-1 and from
the turbine 600 kJmin-1. Determine the power capacity of the turbine, considering the boiler and turbine as a single unit.
