Depth of Water Flow in Channel given Velocity Approach Solution

STEP 0: Pre-Calculation Summary

Formula Used

Depth of Flow = Discharge by Approach Velocity/(Width of Channel1*Velocity of Flow 1)
d_f = Q'/(b*v)
This formula uses 4 Variables

Variables Used

Depth of Flow - (Measured in Meter) - Depth of Flow is the distance from the top or surface of the flow to the bottom of a channel or other waterway or Depth of Flow at the Vertical while measuring Sound Weights.
Discharge by Approach Velocity - (Measured in Cubic Meter per Second) - Discharge by Approach Velocity is the volumetric flow rate (in m 3 /h or ft 3 /h) of water transported through a given cross-sectional area.
Width of Channel1 - (Measured in Meter) - Width of Channel1 is the width of Notch and weir.
Velocity of Flow 1 - (Measured in Meter per Second) - Velocity of Flow 1 is the flow of water over the channel.

STEP 1: Convert Input(s) to Base Unit

Discharge by Approach Velocity: 153 Cubic Meter per Second --> 153 Cubic Meter per Second No Conversion Required
Width of Channel1: 3.001 Meter --> 3.001 Meter No Conversion Required
Velocity of Flow 1: 15.1 Meter per Second --> 15.1 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

d_f = Q'/(b*v) --> 153/(3.001*15.1)

Evaluating ... ...

d_f = 3.37635799104493

STEP 3: Convert Result to Output's Unit

3.37635799104493 Meter --> No Conversion Required

FINAL ANSWER

3.37635799104493 ≈ 3.376358 Meter <-- Depth of Flow

Coefficient of Discharge given Discharge if Velocity considered

LaTeX Go Coefficient of Discharge = (Francis Discharge*3)/(2*(sqrt(2*Acceleration due to Gravity))*(Length of Weir Crest-0.1*Number of End Contraction*Still Water Head)*(Still Water Head^(3/2)-Velocity Head^(3/2)))

Coefficient of Discharge given Discharge if Velocity not considered

LaTeX Go Coefficient of Discharge = (Francis Discharge*3)/(2*(sqrt(2*Acceleration due to Gravity))*(Length of Weir Crest-0.1*Number of End Contraction*Height of Water above Crest of Weir)*Height of Water above Crest of Weir^(3/2))

Coefficient of Discharge given Discharge Passing over Weir considering Velocity

LaTeX Go Coefficient of Discharge = (Francis Discharge with Suppressed End*3)/(2*(sqrt(2*Acceleration due to Gravity))*Length of Weir Crest*((Height of Water above Crest of Weir+Velocity Head)^(3/2)-Velocity Head^(3/2)))

Coefficient of Discharge given Discharge over Weir without considering Velocity

LaTeX Go Coefficient of Discharge = (Francis Discharge with Suppressed End*3)/(2*(sqrt(2*Acceleration due to Gravity))*Length of Weir Crest*Height of Water above Crest of Weir^(3/2))

Depth of Water Flow in Channel given Velocity Approach Formula

LaTeX Go

Depth of Flow = Discharge by Approach Velocity/(Width of Channel1*Velocity of Flow 1)
d_f = Q'/(b*v)

What is Discharge?

In hydrology, discharge is the volumetric flow rate of water that is transported through a given cross-sectional area.

What is a weir?

A weir or low head dam is a barrier across the width of a river that alters the flow characteristics of water and usually results in a change in the height of the river level. They are also used to control the flow of water for outlets of lakes, ponds, and reservoirs.
