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