Three parallel pipes connected at the two ends have flow-rates Q₁, Q2 and Q3 respectively, and the corresponding frictional head losses are hL₁, h₁2 and h₁3 respectively. The correct expressions for total flow rate (Q) and frictional head loss across the two ends (h₁) are (A) Q = Q₁ + Q₂ + Q3; h₁ = hL1 + hL2 + hL3 (B) Q = Q₁ + Q2 + Q3; hL=hL1 = hL2 = hL3 (C) Q = Q₁ = Q2 = Q3; h₁ = h₁1 + h₁2 + h13 (D) Q = Q₁ Q2 = Q3; h₁ = hL1 =hL2 = hL3 =

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.
