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
Steam Boilers, Engines, Nozzles and Turbines Willian's law states that the steam consumption per hour provided with a throttled governor is proportional to (where I.P. = Indicated power) (I.P.)² 1/(I.P) I.P. 1/(I.P)² (I.P.)² 1/(I.P) I.P. 1/(I.P)² ANSWER DOWNLOAD EXAMIANS APP
