Steam Boilers, Engines, Nozzles and Turbines Willian's law states that the steam consumption per hour provided with a throttled governor is proportional to (where I.P. = Indicated power) I.P. (I.P.)² 1/(I.P) 1/(I.P)² I.P. (I.P.)² 1/(I.P) 1/(I.P)² ANSWER DOWNLOAD EXAMIANS APP
Steam Boilers, Engines, Nozzles and Turbines Boiler H.P. is defined as the Steam evaporation rate per kg of fuel fired Work done in evaporating 1 kg of steam per hour from and at 100°C into dry saturated steam Work done by 1 kg of steam at saturation condition The evaporation of 15.65 kg of water per hour from and at 100°C into dry saturated steam Steam evaporation rate per kg of fuel fired Work done in evaporating 1 kg of steam per hour from and at 100°C into dry saturated steam Work done by 1 kg of steam at saturation condition The evaporation of 15.65 kg of water per hour from and at 100°C into dry saturated steam ANSWER DOWNLOAD EXAMIANS APP
Steam Boilers, Engines, Nozzles and Turbines The critical pressure ratio (p₂/p₁) is given by (p₂/p₁) = [(n - 1)/2] n + (1/n) (p₂/p₁) = [(n + 1)/2] n - (1/n) (p₂/p₁) = [2/(n + 1)] n/(n-1) (p₂/p₁) = [2/(n - 1)] n/(n + 1) (p₂/p₁) = [(n - 1)/2] n + (1/n) (p₂/p₁) = [(n + 1)/2] n - (1/n) (p₂/p₁) = [2/(n + 1)] n/(n-1) (p₂/p₁) = [2/(n - 1)] n/(n + 1) ANSWER DOWNLOAD EXAMIANS APP
