Fluid Mechanics With increase in molecular weight of the gas, the head developed by a centrifugal compressor will Unpredictable Decrease Remain same Increase Unpredictable Decrease Remain same Increase ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics The pressure drop per unit length of pipe incurred by a fluid 'X' flowing through pipe is Δp. If another fluid 'Y' having both the specific gravity & density just double of that of fluid 'X', flows through the same pipe at the same flow rate/average velocity, then the pressure drop in this case will be Δp Δp² 2Δp Δp/2 Δp Δp² 2Δp Δp/2 ANSWER DOWNLOAD EXAMIANS APP

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 Length is shorter Sudden expansion of flow in the downstream occurs Distance between the throat and the inlet is more Throat diameter is more Length is shorter Sudden expansion of flow in the downstream occurs Distance between the throat and the inlet is more Throat diameter is more ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics Reynolds number for water flow through a tube of I.D. 5 cm is 1500.
