Steam Boilers, Engines, Nozzles and Turbines The equivalent evaporation is defined as The amount of water evaporated from and at 100°C into dry and saturated steam The evaporation of 15.653 kg of water per hour from and at 100°C The ratio of heat actually used in producing the steam to the heat liberated in the furnace The amount of water evaporated or steam produced in kg per kg of fuel burnt The amount of water evaporated from and at 100°C into dry and saturated steam The evaporation of 15.653 kg of water per hour from and at 100°C The ratio of heat actually used in producing the steam to the heat liberated in the furnace The amount of water evaporated or steam produced in kg per kg of fuel burnt 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) = [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) (p₂/p₁) = [(n - 1)/2] n + (1/n) ANSWER DOWNLOAD EXAMIANS APP
