R G Kennedy Equation for Critical Velocity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Velocity Flow at Bottom of Channel = 0.55*Critical Velocity Ratio*(Water Depth in Channel^0.64)
V^° = 0.55*m*(Y^0.64)
This formula uses 3 Variables

Variables Used

Velocity Flow at Bottom of Channel - (Measured in Meter per Second) - Velocity flow at bottom of channel the vector field that is used to describe fluid motion in a mathematical manner.
Critical Velocity Ratio - Critical velocity ratio the ratio of actual velocity (Va) to critical velocity in channel.
Water Depth in Channel - (Measured in Meter) - Water depth in channel Normal depth is the depth of flow in a channel or culvert when the slope of the water surface and channel bottom is the same and the water depth remains constant.

STEP 1: Convert Input(s) to Base Unit

Critical Velocity Ratio: 1.2 --> No Conversion Required
Water Depth in Channel: 3.6 Meter --> 3.6 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V^° = 0.55*m*(Y^0.64) --> 0.55*1.2*(3.6^0.64)

Evaluating ... ...

V^° = 1.49822671254847

STEP 3: Convert Result to Output's Unit

1.49822671254847 Meter per Second --> No Conversion Required

FINAL ANSWER

1.49822671254847 ≈ 1.498227 Meter per Second <-- Velocity Flow at Bottom of Channel

What is Critical Velocity in Canal?

The critical velocity of a channel is the velocity that is just enough to produce eddies. The possible values of m are listed below: m= 1 for Bari Doab Canal. m<1 If the silt is finer than the Bari Doab canal.

What is Critical Velocity in Kennedy's Theory?

Kennedy's theory: As per Kennedy's theory, critical velocity (Vc) in a channel is the mean velocity which is sufficient to prevent the channel from scouring and silting. Any velocity greater than critical velocity causes scouring in the channel and any velocity less than critical velocity causes silting in the channel.
