A boiler burns coal with a calorific value of 25 MJ/kg. the fluid inside it has initial internal energy of 500 kJ/kg and a final internal energy of 1000 kJ/kg. specific volume of the fluid increases by 10% from 1L/kg and the pressure condition remains constant at 100 kPa. If the amount of fluid required from the boiler is 20 kg/s, how much coal should be burned?

A power plant operates in an idealized Rankine cycle, using water as the working fluid (Figure 3). The steam at the exit of the boiler has a pressure of 6 MPa and temperature of 600 °C (point 1). The water at the exit of the condenser has a pressure of 15 kPa (point 3). The condenser employs a nearby river as the cooling source, which can be regarded to have a constant temperature of 25 °C. The mass flow rate of the steam is 80 kg/s. The hot reservoir has a temperature of 1400 K. Regard water as an incompressible liquid.
