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 Remain unchanged Data insufficient to predict relative pressure drop Increase Decrease Remain unchanged Data insufficient to predict relative pressure drop Increase Decrease ANSWER DOWNLOAD EXAMIANS APP
