Medium

The values of enthalpy of steam at the inlet and outlet of a steam turbine in a Rankine cycle are 2800 kJ/kg and 1800 kJ/kg respectively. Neglecting pump work, the specific steam consumption in kg/kW-hour is

  • 3.60
  • B0.36
  • C0.06
  • D0.01

Explanation

Specific steam consumption = 3600/(h1-h2) kg/kWh = 3600/(2800-1800) = 3600/1000 = 3.60 kg/kWh.
