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 Δp/2 2Δp Δp Δp² Δp/2 2Δp Δp ANSWER DOWNLOAD EXAMIANS APP
