Steam Boilers, Engines, Nozzles and Turbines An economiser is installed in a boiler primarily to Superheat the steam Reduce fuel consumption Increase steam pressure All of the listed here Superheat the steam Reduce fuel consumption Increase steam pressure All of the listed here 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
Steam Boilers, Engines, Nozzles and Turbines The efficiency of a boiler is defined as None of these Ratio of the mass of steam produced to the mass of total water supplied in a given time Ratio of the heat liberated in the furnace to the heat actually used in producing steam Ratio of heat actually used in producing steam to the heat liberated in the furnace None of these Ratio of the mass of steam produced to the mass of total water supplied in a given time Ratio of the heat liberated in the furnace to the heat actually used in producing steam Ratio of heat actually used in producing steam to the heat liberated in the furnace ANSWER DOWNLOAD EXAMIANS APP
