Question 10

A thermal power plant operates on a regenerative cycle with a single open feedwater heater, as shown in the figure. For the state points shown, the specific enthalpies are: h1= 2800 kJ/kg and h2= 200 kJ/kg. The bleed to the feedwater heater is 20% of the boiler steam generation rate. The specific enthalpy at state 3 is?

Question 11

In a gas turbine, hot combustion products with the specific heats cp= 0.98 kJ/kgK, and cv= 0.7538 kJ/kgK enters the turbine at 20 bar, 1500 K and exits at 1 bar. The isentropic efficiency of the turbine is 0.94. The work developed by the turbine per kg of gas flow is?

Question 12

Consider an actual regenerative Rankine cycle with one open feed water heater. For each kg steam entering the turbine, if m kg steam with a specific enthalpy of h1is blade from the turbine, and the specific enthalpy of liquid water entering the heater is h2, then h3the specific enthalpy of saturated liquid leaving the heater is equal to, A rigid container of volume 0.5 m3contains 1.0 kg of water at 120C (vf= 0.00106 m3/kg, vg= 0.8908 m3/kg). The state of water is?

Question 13

For water at 25C, dps/dTs= 0.189 kPa/K (psis the saturation pressure in kPa and Tsis the saturation temperature in K) and the specific volume of dry saturated vapour is 43.38 m3/ kg. Assume that the specific volume of liquid is negligible in comparison with that of vapour. Using the Clausius-Clapeyron equation, an estimate of the enthalpy of evaporation of water at 25C (in kJ/kg) is, A pure substance at 8 MPa and 400C is having a specific internal energy of 2864 kJ/kg and a specific volume of 0.03432 m3/kg. Its specific enthalpy (in kJ/kg) is?

Question 14

1.5 kg of water is in saturated liquid state at 2 bar (vf= 0.001061 m3/kg, uf= 504.0 kJ/kg, hf= 505 kJ/kg). Heat is added in a constant pressure process till the temperature of water reaches 400C (v = 1.5493 m3/kg, u = 2967.0 k J/kg, h = 3277.0 kJ/kg). The heat added (in kJ) in the process is, A steel billet of 2000 kg mass is to be cooled from 1250 K to 450 K. The heat released during this process is to be used as a source of energy. The ambient temperature is 303 K and specific heat of steel is 0.5 kJ/kgK. The available energy of this billet is?r
