- In case of a rotameter, the density of the float material is __________ that of the liquid it replaces.
- In Newton's law range, the terminal velocity of a solid spherical particle falling through a stationary fluid mass varies as the __________ of its diameter.
- Which of the following has the maximum compression ratio?
- Umf is the minimum fluidisation velocity for a bed of particles. An increase in the superficial gas velocity from 2 Umf to 2.5 Umf results in (all velocities are smaller than the entrainment velocity of the particles) no change in the
- Foot valve provided in the pump is a __________ valve.
- A Pitot tube indicates 5 cm of water (manometer) when it is being used for measuring velocity of air. The velocity of air in m/sec is
- For flow through an orifice from a reservoir, the actual velocity at the vena con-tracta is given by
- In open channel flow in a rectangular channel, the ratio between the critical depth and the initial depth, when a hydraulic jump occurs is
