Steam Boilers, Engines, Nozzles and Turbines The velocity of flue gases (V) through the chimney under a static draught of (H') metres is given by V = 2g/H' V = 2gH' V = H'/2g V = 2g H' V = 2g/H' V = 2gH' V = H'/2g V = 2g H' ANSWER DOWNLOAD EXAMIANS APP
Steam Boilers, Engines, Nozzles and Turbines The principal function of a stop valve is to 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 Put off fire in the furnace of the boiler when the level of water in the boiler falls to an unsafe limit Control the flow of steam from the boiler to the main pipe and to shut off the steam completely when required 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 Put off fire in the furnace of the boiler when the level of water in the boiler falls to an unsafe limit Control the flow of steam from the boiler to the main pipe and to shut off the steam completely when required ANSWER DOWNLOAD EXAMIANS APP
