Fluid Mechanics Reynolds number for water flow through a tube of I.D. 5 cm is 1500. If a liquid of 5 centipoise viscosity and 0.8 specific gravity flows in the same pipe at the same velocity, then the pressure drop will Remain same Decrease Data insufficient to predict pressure drop Increase Remain same Decrease Data insufficient to predict pressure drop Increase 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 Remain unchanged Increase Data insufficient to predict relative pressure drop Decrease Remain unchanged Increase Data insufficient to predict relative pressure drop ANSWER DOWNLOAD EXAMIANS APP
