Civil Engineering
In a uniform open channel flow:
The total energy remains constant along the channel
The total energy line either rises or falls along the channeldepending on the state of the flow
The specific energy decreases along the channel
The line representing the total energy is parallel to the bedof the channel
In which of the following situations, the flow is uniform?
Flow in channel contraction or expansion
Flow in the vicinity of a bridge pier
Flow at the middle of a long prismatic channel far away fromthe obstruction
Uniform flow in an open channel exists when the flow is steady,and the channel is
Prismatic
Non-prismatic and the depth of the flow is constant along thechannel
Prismatic and the depth of the flow is constant along thechannel
Frictionless
In uniform flow, there is a balance between:
Gravity and frictional forces
Gravity and inertial forces
Inertial and frictional forces
Inertial and viscous forces
The water depth in a wide channel is equal to 1.2m (For a verywide channel R is approximately equal to y). If the Chezycoefficient is equal to 49 (metric), then Manning coefficient n(metric) is equal to:
0.024
0.021
0.026
