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 = a + b × I.P. I.P. = b × m + a m = (b/I.P.) - a I.P. = a × m + b m = a + b × I.P. I.P. = b × m + a m = (b/I.P.) - a I.P. = a × m + b ANSWER DOWNLOAD EXAMIANS APP
