Fluid Mechanics The energy loss in flow through ven-turimeter is less than that through flow nozzle, because in case of a flow nozzle, the Throat diameter is more Sudden expansion of flow in the downstream occurs Length is shorter Distance between the throat and the inlet is more Throat diameter is more Sudden expansion of flow in the downstream occurs Length is shorter Distance between the throat and the inlet is more ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics Water hammer is caused, when water flowing in a pipe is suddenly brought to rest by closing the valve. The extent of pressure thus produced due to water hammer depends on the Fluid velocity in the pipe Time taken to close the valve All of these Pipe length Fluid velocity in the pipe Time taken to close the valve All of these Pipe length ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics A centrifugal pump is used to pump water through a horizontal distance of 150 m, and then raised to an overhead tank 10 m above. The pipe is smooth with an I.D of 50 mm. What head (m of water) must the pump generate at its exit (E) to deliver water at a flow rate of 0.001 m³/s?
