Open Channel Flow FAQs
What is channel transition?
A transition is a portion of a channel with a varying cross-section that connects one uniform flow channel to another uniform flow channel.
Define Specific Force and Specific Energy in Open Channel Flow.
Specific energy in Open Channel Flow is the total head with respect to the channel bottom. It is a summation of the velocity head and the depth of flow at a given cross section. Specific force is defined as the non-gravitational force per unit mass
Define Economical Channel and Most Efficient Channel.
A section is said to be economical when its construction cost is minimum for a given discharge. And a section is said to be most efficient if, for a given cross-sectional area, the discharge carrying capacity is maximum.
Give some uses of a channel transition?
Uses of channel transition include metering of flow, dissipation of channel energy, reduction or increase of velocities, change of channel section or alignment with a minimum energy dissipation.
Define Alternate depth and Conjugate depth?
Two depths having equal specific energies are called Alternate Depths. Two depths having the same specific forces are called Conjugate or Sequent Depths.
