Mechanical Engineering

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
