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). F = f₁ + f₂ + f₃ V₁ = V₂ = V₃ Q = Q₁ + Q₂ + Q₃ Q₁ = Q₂ = Q₃ F = f₁ + f₂ + f₃ V₁ = V₂ = V₃ Q = Q₁ + Q₂ + Q₃ Q₁ = Q₂ = Q₃ ANSWER DOWNLOAD EXAMIANS APP
