Steam Boilers, Engines, Nozzles and Turbines Which of the following statement is correct for a compound steam engine? The temperature range per cylinder is increased, with corresponding increase in condensation The ratio of expansion is reduced, thus reducing the length of stroke 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 temperature range per cylinder is increased, with corresponding increase in condensation The ratio of expansion is reduced, thus reducing the length of stroke 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 ANSWER DOWNLOAD EXAMIANS APP
