Steam Boilers, Engines, Nozzles and Turbines The critical pressure ratio (p₂/p₁) is given by (p₂/p₁) = [2/(n + 1)] n/(n-1) (p₂/p₁) = [(n - 1)/2] n + (1/n) (p₂/p₁) = [2/(n - 1)] n/(n + 1) (p₂/p₁) = [(n + 1)/2] n - (1/n) (p₂/p₁) = [2/(n + 1)] n/(n-1) (p₂/p₁) = [(n - 1)/2] n + (1/n) (p₂/p₁) = [2/(n - 1)] n/(n + 1) (p₂/p₁) = [(n + 1)/2] n - (1/n) ANSWER DOWNLOAD EXAMIANS APP
