Capillary rise of water is
Capillary rise or capillarity is a phenomenon in which liquid spontaneously rises or falls in a narrow space such as a thin tube or in the voids of a porous material.

See lessFor maximum velocity of flow, the depth of water in the circular channel must
It is calculated using the Manning's equation or the Chezy's equation. In this case, we are given the diameter of the circular channel section as 1.5 m. Therefore, the depth of flow for maximum velocity in a circular channel section with a diameter of 1.5 m is 1.215 m. Hence, the correct answer is oRead more
It is calculated using the Manning’s equation or the Chezy’s equation. In this case, we are given the diameter of the circular channel section as 1.5 m. Therefore, the depth of flow for maximum velocity in a circular channel section with a diameter of 1.5 m is 1.215 m. Hence, the correct answer is option C) 1.215 m.
See lessFor uniform flow in canals
The flow in channel is said to be uniform if the depth, slope, cross-section and velocity remain constant over a given length of the channel. The flow in uniform flow is uniform through out the cross section without change of velocity. A uniform flows are possible only in prismatic channel only.

See lessThe shape of fire hose nozzle is generally kept
The hose nozzle is cylindrical in shape with the continuous decrease in its size, i.e. the convergent shape. The general purpose of a hose nozzle is to supply the flow of water at high velocity and reduced pressure so a convergent nozzle is used for a fire hose nozzle.
