Steam Boilers, Engines, Nozzles and Turbines Blow off cock in a boiler is used to Control the flow of steam from the boiler to the main pipe and to shut off the steam completely when required Put off fire in the furnace of the boiler when the level of water in the boiler falls to an unsafe limit Increase the temperature of saturated steam without raising its pressure Empty the boiler when required and to discharge the mud, scale or sediments which are accumulated at the bottom of the boiler Control the flow of steam from the boiler to the main pipe and to shut off the steam completely when required Put off fire in the furnace of the boiler when the level of water in the boiler falls to an unsafe limit Increase the temperature of saturated steam without raising its pressure Empty the boiler when required and to discharge the mud, scale or sediments which are accumulated at the bottom of the boiler 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
