The boiler efficiency is given by (where m = Total mass of water evaporated into steam in kg/h, m_{f} = Mass of fuel in kg/h, C = Calorific valve of fuel in kJ/kg of fuel, h = Total heat of steam in kJ/kg, and h_{f1} = Sensible heat of feed water in kJ /kg)
Which of the following is correct ? (where p_{a} = Actual mean effective pressure, p_{m} = Theoretical mean effective pressure, and K = Diagram factor)
Willian's law states that the steam consumption per hour provided with a throttled governor is proportional to (where I.P. = Indicated power)
When the total heat of steam is h kJ/kg and the sensible heat of feed water is h_{f1} kJ/kg, then the factor of evaporation is given by
