- Select the wrong statement pertaining to flow of an incompressible fluid through a venturimeter.
- Two fluids are flowing through two similar pipes of the same diameter. The Reynold's number is same. For the same flow rate if the viscosity of a fluid is reduced to half the value of the first fluid, the pressure drop will

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 - A venturimeter can not be used for the direct measurement of
