Fluid Mechanics In case of supersonic flow of a fluid through pipeline, the 'Mach number' is 1 > 1 < 1 1 > 1 < 1 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 2Δp Δp² Δp/2 Δp 2Δp Δp² Δp/2 ANSWER DOWNLOAD EXAMIANS APP
