Steam Boilers, Engines, Nozzles and Turbines Which of the following statement is correct for a compound steam engine? The forces in the working parts are increased as the forces are distributed over more parts The ratio of expansion is reduced, thus reducing the length of stroke The temperature range per cylinder is increased, with corresponding increase in condensation The cost of the engine, for the same power and economy, is more than that of a simple steam engine The forces in the working parts are increased as the forces are distributed over more parts The ratio of expansion is reduced, thus reducing the length of stroke The temperature range per cylinder is increased, with corresponding increase in condensation The cost of the engine, for the same power and economy, is more than that of a simple steam engine 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 = a + b × I.P. m = (b/I.P.) - a I.P. = a × m + b I.P. = b × m + a m = a + b × I.P. m = (b/I.P.) - a I.P. = a × m + b I.P. = b × m + a ANSWER DOWNLOAD EXAMIANS APP
