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 = (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 V/Vmax = (x/r)1/7 V/Vmax = (x.r)1/7 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 Decrease Increase Data insufficient to predict relative pressure drop Remain unchanged Decrease Increase Data insufficient to predict relative pressure drop Remain unchanged ANSWER DOWNLOAD EXAMIANS APP
