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 Pipe length Time taken to close the valve All of these Fluid velocity in the pipe Pipe length Time taken to close the valve All of these ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics If three pipes of different diameters, lengths & friction factors are connected in parallel, then (where, Q = flow rate, V= fluid velocity f = friction factor). Q₁ = Q₂ = Q₃ V₁ = V₂ = V₃ F = f₁ + f₂ + f₃ Q = Q₁ + Q₂ + Q₃ Q₁ = Q₂ = Q₃ V₁ = V₂ = V₃ F = f₁ + f₂ + f₃ Q = Q₁ + Q₂ + Q₃ ANSWER DOWNLOAD EXAMIANS APP
