Fluid Mechanics The energy loss in flow through ven-turimeter is less than that through flow nozzle, because in case of a flow nozzle, the Throat diameter is more Sudden expansion of flow in the downstream occurs Length is shorter Distance between the throat and the inlet is more Throat diameter is more Sudden expansion of flow in the downstream occurs Length is shorter Distance between the throat and the inlet is more 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
