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 Δp² 2Δp Δp Δp/2 Δp² 2Δp Δp Δp/2 ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics As the velocity V and thus the Reynolds number of a flow past a sphere increases from very low value, the drag force for Re << 1 Increases linearly with V Decreases as V² None of these Decreases linearly with V Increases linearly with V Decreases as V² None of these Decreases linearly with V ANSWER DOWNLOAD EXAMIANS APP
