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 2Δp Δp Δp/2 Δp² 2Δp Δp Δp/2 Δp² ANSWER DOWNLOAD EXAMIANS APP
Fluid Mechanics A bed of spherical particles (specific gravity 2.5) of uniform size 1500 μm is 0.5 m in diameter and 0.5 m high. In packed bed state, the porosity may be taken as 0.4. Ergun's equation for the above fluid-particle system (in SI units) is given below : Δ P/L = 375 x 10³ VOM + 10.94 x 10⁶ V²OM (SI units) If water is to be used as the fluidising medium, the minimum fluidisation velocity, VOM is 12 mm/s 28 mm/s 24 mm/s 16 mm/s 12 mm/s 28 mm/s 24 mm/s 16 mm/s ANSWER DOWNLOAD EXAMIANS APP
