- Pitot tube measures the __________ of a fluid.
- What is the maximum theoretical suction lift (metres) of a reciprocating pump?
- In an incompressible fluid, the density is
- The flow of gas along a pipe in the direction of decreasing pressure causes decrease in its
- A 0.5 m high bed made up of a 1 mm dia glass sphere (density 2500 kg/m³ ) is to be fluidised by water (density 1000 kg/m³ ). If at the point of incipient fluidisation, the bed voidage is 40%, the pressure drop across the bed is
- The maximum depth from which a centrifugal pump can draw water is
-
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, in actual operation, the above bed has a height = 1 m. What is the porosity of the fluidised bed ? - If the discharge of a centrifugal pump is throttled, then its suction lift
- The pressure head on sudden contraction in a horizontal pipe is converted into the __________ head.
