Fluid Mechanics For turbulent fluid flow in pipe, the expression for Prandtl one seventh power law is (where, r = pipe radius, x = distance). V/Vmax = (x/r)1/7 V/Vmax = (x.r)1/7 V/Vmax = (r/x)1/7 None of these V/Vmax = (x/r)1/7 V/Vmax = (x.r)1/7 V/Vmax = (r/x)1/7 None of these 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 2Δp Δp² Δp Δp/2 2Δp Δp² Δp ANSWER DOWNLOAD EXAMIANS APP
