Steam Boilers, Engines, Nozzles and Turbines When steam after doing work in the cylinder passes into a condenser, the engine is said to be a Condensing steam engine Vertical steam engine Slow speed engine Non-condensing steam engine Condensing steam engine Vertical steam engine Slow speed engine Non-condensing steam engine ANSWER DOWNLOAD EXAMIANS APP
Steam Boilers, Engines, Nozzles and Turbines In a reaction turbine The pressure and temperature of steam remains constant The steam is allowed to expand in the nozzle, where it gives a high velocity before it enters the moving blades The steam is expanded from a high pressure to a condenser pressure in one or more nozzles The expansion of steam takes place partly in the fixed blades and partly in the moving blades The pressure and temperature of steam remains constant The steam is allowed to expand in the nozzle, where it gives a high velocity before it enters the moving blades The steam is expanded from a high pressure to a condenser pressure in one or more nozzles The expansion of steam takes place partly in the fixed blades and partly in the moving blades ANSWER DOWNLOAD EXAMIANS APP

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 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 ANSWER DOWNLOAD EXAMIANS APP
