With decrease in the capacity of the pump, the __________ decreases. BHP required by the pump Head of the liquid pumped NPSH required All of these BHP required by the pump Head of the liquid pumped NPSH required All of these 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/2 2Δp Δp Δp² Δp/2 2Δp Δp Δp² ANSWER DOWNLOAD EXAMIANS APP
