Question

The variation of saturation pressure with saturation temperature for a liquid is 0.1 bar/K at 400K. The specific volume of saturated liquid and dry saturated vapour at 400 K are 0.251 m³/kg and 0.001 m³/kg. The value of latent heat of vaporization using Clausius Clapeyron equation is

(a) 16000 kJ/kg           (b) 1600 kJ/kg

(c) 1000 kJ/kg             (d) 160 kJ/kg
