First Law of Thermodynamics
GATE 2020
Medium
For an ideal Rankine cycle operating between pressures of 30 bar and 0.04 bar, the work output from the turbine is 903 kJ/kg and the work input to the feed pump is 3 kJ/kg. The specific steam consumption is __________ kg/kW.h (round off to 2 decimal places).
4 kg/kW.h(± 0.02 accepted)
Explanation
Net work = 903−3 = 900 kJ/kg. Specific steam consumption = 3600/Wnet = 3600/900 = 4.00 kg/kWh.
