Steam enters the first turbine stage at 7 MPa and 550°C and expands to 700 kPa, where some of the steam is extracted and diverted to a closed feed water heater. Condensate exiting the feed- water heater as saturated liquid at 700 kPa passes through a trap into the condenser. The feed- water exits the heater at 7 MPa with a temperature of 175°C. The condenser pressure is 8 kPa. If the power developed is 100MW, determine: the thermal mass flow rate into the first stage turbine. (mal efficiency of the cycle, and (b) the sre

Homwork-6.png Homework-6 P.1 Calculate the dryness fraction (quality) of steam which has 1.5 Kg of water in suspension with 50 Kg of steam? A vessel having a volume of 0.05 m contains a mixture of saturated water and saturated steam at a temperature of 245 ° C. The mass of liquid present is 10 Kg. P.2 Find the following: (a) The pressure. (b) The mass. (c) The specific volume. (d) The specific enthalpy (e) The specific entropy. (f) The specific internal energy.

Q2 An engine using fuel of calorific value 42000 kj/kg has abrake thermal efficiency of 30% Find its brake specific fuel consumption in gram b.p-hr Answer C 285.71 gm/Kw-hr]

Air from the discharge of a compressor enters a 1 m3 storage tank. The initial air pressure in the tank is 500kPa, and the temperature is 600 ⁰K. The tank cools, and the internal energy decreases by 213 kJ/kg. Determine the ff: a.) The Work done, b.) The heat Loss (unit in KJ), c.) The change in enthalpy, d.) The final Temperature.

temperature). 14. When an individual is in water, the convective heat loss term is grea:ty increased. For water immersion, K. 16.5 kcal/m hr C. Assuming the BMR of a resting man is 72 kcal/hr, find the water temperature at which the water heat loss is just balanced by the BMR. Assume A, 1.75 m2 and T, 34°C.

Provide clear and complete solution as well as diagram. The discharge pressure of an air compressor is 8 times the suction pressure. If volume flow at suction is 0.23 m3/s, what is the compressor power assuming n equals 1.35 and suction pressure is 97 kPa? A. 64.58 kW                C. 60.45 kWB. 61.48 kW                D. 71.5 kW
