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 V₁ = V₂ = V₃ Q₁ = Q₂ = Q₃ F = f₁ + f₂ + f₃ Q = Q₁ + Q₂ + Q₃ V₁ = V₂ = V₃ Q₁ = Q₂ = Q₃ F = f₁ + f₂ + f₃ ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics Two fluids are flowing through two similar pipes of the same diameter. The Reynold's number is same. For the same flow rate if the viscosity of a fluid is reduced to half the value of the first fluid, the pressure drop will Data insufficient to predict relative pressure drop Remain unchanged Increase Decrease Data insufficient to predict relative pressure drop Remain unchanged Increase Decrease ANSWER DOWNLOAD EXAMIANS APP
