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 Time taken to close the valve Pipe length All of these Fluid velocity in the pipe Time taken to close the valve Pipe length All of these Fluid velocity in the pipe ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics In case of hydraulically smooth pipe, the resistance to flow depends only on the Reynolds number, whereas for a hydraulically rough pipe, the resistance to flow is governed by the relative roughness. Two pipes are said to have the same hydraulic roughness, when they have equal values of Relative roughness Friction co-efficient for flows at equal Reynold number Absolute roughness All of these Relative roughness Friction co-efficient for flows at equal Reynold number Absolute roughness All of these ANSWER DOWNLOAD EXAMIANS APP
