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). Q = Q₁ + Q₂ + Q₃ Q₁ = Q₂ = Q₃ V₁ = V₂ = V₃ F = f₁ + f₂ + f₃ Q = Q₁ + Q₂ + Q₃ Q₁ = Q₂ = Q₃ V₁ = V₂ = V₃ F = f₁ + f₂ + f₃ ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics The pressure drop per unit length of pipe incurred by a fluid 'X' flowing through pipe is Δp. If another fluid 'Y' having both the specific gravity & density just double of that of fluid 'X', flows through the same pipe at the same flow rate/average velocity, then the pressure drop in this case will be Δp/2 Δp Δp² 2Δp Δp/2 Δp Δp² 2Δp ANSWER DOWNLOAD EXAMIANS APP
