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 2Δp Δp² Δp/2 Δp 2Δp Δp² Δp/2 Δp ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics For turbulent fluid flow in pipe, the expression for Prandtl one seventh power law is (where, r = pipe radius, x = distance). None of these V/Vmax = (x/r)1/7 V/Vmax = (r/x)1/7 V/Vmax = (x.r)1/7 None of these V/Vmax = (x/r)1/7 V/Vmax = (r/x)1/7 V/Vmax = (x.r)1/7 ANSWER DOWNLOAD EXAMIANS APP
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). V₁ = V₂ = V₃ Q₁ = Q₂ = Q₃ F = f₁ + f₂ + f₃ Q = Q₁ + Q₂ + Q₃ V₁ = V₂ = V₃ Q₁ = Q₂ = Q₃ F = f₁ + f₂ + f₃ Q = Q₁ + Q₂ + Q₃ ANSWER DOWNLOAD EXAMIANS APP
