Fluid Mechanics As the velocity V and thus the Reynolds number of a flow past a sphere increases from very low value, the drag force for Re << 1 Decreases as V² Decreases linearly with V None of these Increases linearly with V Decreases as V² Decreases linearly with V None of these Increases linearly with V 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 Pipe length Fluid velocity in the pipe All of these Time taken to close the valve Pipe length Fluid velocity in the pipe All of these Time taken to close the valve ANSWER DOWNLOAD EXAMIANS APP
