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 Q = Q₁ + Q₂ + Q₃ V₁ = V₂ = V₃ F = f₁ + f₂ + f₃ Q₁ = Q₂ = Q₃ Q = Q₁ + Q₂ + Q₃ V₁ = V₂ = V₃ F = f₁ + f₂ + f₃ ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics A 2" gate valve fitted in a pipe is replaced by a similar globe valve. Pressure drop in gate valve was Δp. For the same discharge, the pressure drop across globe valve is < Δp > Δp Δp Δp² < Δp > Δp Δp Δp² ANSWER DOWNLOAD EXAMIANS APP
