Uniform flow is said to occur when-

  1. Size and shape of the cross section in a particular length remains constant
  2. Size and shape of the cross section change along a length
  3. The flow is steady
  4. The flow is stream line

Answer: A. Size and shape of the cross section in a particular length remains constant.

Uniform flow is said to occur when size and shape of the cross section in a particular length remains constant.

Solution

The flow of a fluid in which each particle moves along its line of flow with constant speed and in which the cross-section of each stream tube remains unchanged is known as Uniform flow.

  • For uniform flow, the velocity, depth, and cross sectional area are constant along the channel; whereas for nonuniform flow, they vary in the direction of the flow.
  • Uniform flow is said to occur when size and shape of the cross section in a particular length remains constant
  • Example uniform flow: A steady flow through a long straight pipe of a constant diameter.
