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 Sudden expansion of flow in the downstream occurs Throat diameter is more Distance between the throat and the inlet is more Length is shorter Sudden expansion of flow in the downstream occurs Throat diameter is more Distance between the throat and the inlet is more Length is shorter 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 Increase Decrease Data insufficient to predict relative pressure drop Remain unchanged Increase Decrease Data insufficient to predict relative pressure drop Remain unchanged ANSWER DOWNLOAD EXAMIANS APP
