Steam Boilers, Engines, Nozzles and Turbines The maximum discharge of steam through a convergent-divergent nozzle depends upon Initial pressure and volume of steam Final pressure of steam leaving the nozzle Both (A) and (B) Area of nozzle at throat Initial pressure and volume of steam Final pressure of steam leaving the nozzle Both (A) and (B) Area of nozzle at throat 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) I.P. = b × m + a m = a + b × I.P. I.P. = a × m + b m = (b/I.P.) - a I.P. = b × m + a m = a + b × I.P. I.P. = a × m + b m = (b/I.P.) - a ANSWER DOWNLOAD EXAMIANS APP
