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 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 Pipe length ANSWER DOWNLOAD EXAMIANS APP
