Steam Boilers, Engines, Nozzles and Turbines The function of a flywheel is To convert rotary motion of the crankshaft into to and fro motion of the valve rod To keep the engine speed uniform at all load conditions To prevent fluctuation of speed To convert reciprocating motion of the piston into rotary motion To convert rotary motion of the crankshaft into to and fro motion of the valve rod To keep the engine speed uniform at all load conditions To prevent fluctuation of speed To convert reciprocating motion of the piston into rotary motion ANSWER DOWNLOAD EXAMIANS APP
Steam Boilers, Engines, Nozzles and Turbines The high pressure and low pressure cylinders in a Woolf type compound engine are regarded as having cranks None of these 90° to each other 0° to each other 180° to each other None of these 90° to each other 0° to each other 180° to each other ANSWER DOWNLOAD EXAMIANS APP
Steam Boilers, Engines, Nozzles and Turbines The critical pressure ratio (p₂/p₁) is given by (p₂/p₁) = [2/(n + 1)] n/(n-1) (p₂/p₁) = [2/(n - 1)] n/(n + 1) (p₂/p₁) = [(n - 1)/2] n + (1/n) (p₂/p₁) = [(n + 1)/2] n - (1/n) (p₂/p₁) = [2/(n + 1)] n/(n-1) (p₂/p₁) = [2/(n - 1)] n/(n + 1) (p₂/p₁) = [(n - 1)/2] n + (1/n) (p₂/p₁) = [(n + 1)/2] n - (1/n) ANSWER DOWNLOAD EXAMIANS APP
