The following data collected from a steam turbine of 25 MWcapacity thermal power plant:
Assume R for air as 287 kJ/kg C
Steam condensed = 40000 kh/hr
Temperaure of steam in condenser =40 degree
Dryness of steam enetring condenser = 0.85
Air leakage in the condenser = 140 kg/hr
Temperature of codenser =35 degree
Temperature at the suction of air pump = 32 degree
Borometer reading = 76 cm of Hg
Maximum rise in cooling water temperature =12 degree
Find : 1. Vacuum gauge reading in condenser , 2.Capacity of dryair pump in cume meter per hour 3.Quantity of cooling water passesthrough condenser in tons per hour
