Steam Boilers, Engines, Nozzles and Turbines Which of the following statement is correct for a compound steam engine? The cost of the engine, for the same power and economy, is more than that of a simple steam engine The temperature range per cylinder is increased, with corresponding increase in condensation 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 cost of the engine, for the same power and economy, is more than that of a simple steam engine The temperature range per cylinder is increased, with corresponding increase in condensation 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 ANSWER DOWNLOAD EXAMIANS APP

Steam Boilers, Engines, Nozzles and Turbines The principal function of a stop valve is to Control the flow of steam from the boiler to the main pipe and to shut off the steam completely when required Put off fire in the furnace of the boiler when the level of water in the boiler falls to an unsafe limit Empty the boiler when required and to discharge the mud, scale or sediments which are accumulated at the bottom of the boiler Increase the temperature of saturated steam without raising its pressure Control the flow of steam from the boiler to the main pipe and to shut off the steam completely when required Put off fire in the furnace of the boiler when the level of water in the boiler falls to an unsafe limit Empty the boiler when required and to discharge the mud, scale or sediments which are accumulated at the bottom of the boiler Increase the temperature of saturated steam without raising its pressure ANSWER DOWNLOAD EXAMIANS APP
