Steam Boilers, Engines, Nozzles and Turbines Which of the following is correct? (Where pa = Actual mean effective pressure, pm = Theoretical mean effective pressure, and K = Diagram factor) pa = K/pm pa = pm/K pa = pm + K pa = pm × K pa = K/pm pa = pm/K pa = pm + K pa = pm × K ANSWER DOWNLOAD EXAMIANS APP
Steam Boilers, Engines, Nozzles and Turbines Willian’s line follows the law (where b = A constant representing the shape of the Willian’s line, a = Another constant i.e. no load consumption per hour, I.P. = Indicated power, and m = Steam consumption per hour) m = (b/I.P.) - a m = a + b × I.P. I.P. = a × m + b I.P. = b × m + a m = (b/I.P.) - a m = a + b × I.P. I.P. = a × m + b I.P. = b × m + a ANSWER DOWNLOAD EXAMIANS APP
