Discharge given Velocity Approach Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
Velocity of Flow 1 - (Measured in Meter per Second) - Velocity of Flow 1 is the flow of water over the channel.
Width of Channel1 - (Measured in Meter) - Width of Channel1 is the width of Notch and weir.
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.

STEP 1: Convert Input(s) to Base Unit

Velocity of Flow 1: 15.1 Meter per Second --> 15.1 Meter per Second No Conversion Required
Width of Channel1: 3.001 Meter --> 3.001 Meter No Conversion Required
Depth of Flow: 3.3 Meter --> 3.3 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Q' = v*(b*d_f) --> 15.1*(3.001*3.3)

Evaluating ... ...

Q' = 149.53983

STEP 3: Convert Result to Output's Unit

149.53983 Cubic Meter per Second --> No Conversion Required

FINAL ANSWER

149.53983 ≈ 149.5398 Cubic Meter per Second <-- Discharge by Approach Velocity

Discharge considering Approach Velocity

LaTeX Go Francis Discharge = (2/3)*Coefficient of Discharge*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))

Discharge Passing over Weir considering Velocity

LaTeX Go Francis Discharge with Suppressed End = (2/3)*Coefficient of Discharge*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))

Discharge over Weir without considering Velocity

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

Discharge given Velocity Approach

LaTeX Go Discharge by Approach Velocity = Velocity of Flow 1*(Width of Channel1*Depth of Flow)

Discharge given Velocity Approach Formula

LaTeX Go

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

What is Velocity of Approach?

The Velocity Approach (Va) is defined as the rate of change of relative displacement between two bodies (i.e. how fast a body approaches another body ).

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.
