Velocity of liquid at C-C for Hc, Ha, and H Solution

STEP 0: Pre-Calculation Summary

Formula Used

Velocity of Liquid Inlet = sqrt(2*9.81*(Atmospheric Pressure Head+Constant Head-Absolute Pressure Head))
V_i = sqrt(2*9.81*(H_a+H_c-H_AP))
This formula uses 1 Functions, 4 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Velocity of Liquid Inlet - (Measured in Meter per Second) - The Velocity of liquid inlet is considered on flow through an external cylindrical mouthpiece.
Atmospheric Pressure Head - (Measured in Meter) - The Atmospheric Pressure Head is considered for the liquid at venacontracta.
Constant Head - (Measured in Meter) - The Constant head is considered for discharging of the water from an mouthpiece.
Absolute Pressure Head - (Measured in Meter) - The Absolute Pressure Head is considered for the liquid at venacontracta.

STEP 1: Convert Input(s) to Base Unit

Atmospheric Pressure Head: 7 Meter --> 7 Meter No Conversion Required
Constant Head: 10.5 Meter --> 10.5 Meter No Conversion Required
Absolute Pressure Head: 14 Meter --> 14 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_i = sqrt(2*9.81*(H_a+H_c-H_AP)) --> sqrt(2*9.81*(7+10.5-14))

Evaluating ... ...

V_i = 8.28673639015988

STEP 3: Convert Result to Output's Unit

8.28673639015988 Meter per Second --> No Conversion Required

FINAL ANSWER

8.28673639015988 ≈ 8.286736 Meter per Second <-- Velocity of Liquid Inlet

Time of Emptying Hemispherical Tank

Go Total Time Taken = (pi*(((4/3)*Hemispherical Tank Radius*((Initial Height of Liquid^1.5)-(Final Height of Liquid^1.5)))-(0.4*((Initial Height of Liquid^(5/2))-(Final Height of Liquid)^(5/2)))))/(Coefficient of Discharge*Area of Orifice*(sqrt(2*9.81)))

Time of Emptying Circular Horizontal Tank

Go Total Time Taken = (4*Length*((((2*Radius 1)-Final Height of Liquid)^(3/2))-((2*Radius 1)-Initial Height of Liquid)^(3/2)))/(3*Coefficient of Discharge*Area of Orifice*(sqrt(2*9.81)))

Time of Emptying Tank through Orifice at Bottom

Go Total Time Taken = (2*Area of Tank*((sqrt(Initial Height of Liquid))-(sqrt(Final Height of Liquid))))/(Coefficient of Discharge*Area of Orifice*sqrt(2*9.81))

Velocity of liquid at C-C for Hc, Ha, and H

Go Velocity of Liquid Inlet = sqrt(2*9.81*(Atmospheric Pressure Head+Constant Head-Absolute Pressure Head))

Coefficient of velocity for horizontal and vertical distance

Go Coefficient of Velocity = Horizontal Distance/(sqrt(4*Vertical Distance*Head of the Liquid))

Coefficient of Velocity given Head Loss

Go Coefficient of Velocity = sqrt(1-(Head Loss/Head of the Liquid))

Coefficient of velocity

Go Coefficient of Velocity = Actual Velocity/Theoretical Velocity

Theoretical velocity

Go Velocity = sqrt(2*9.81*Pelton Head)

Velocity of liquid at C-C for Hc, Ha, and H Formula

Velocity of Liquid Inlet = sqrt(2*9.81*(Atmospheric Pressure Head+Constant Head-Absolute Pressure Head))
V_i = sqrt(2*9.81*(H_a+H_c-H_AP))

What is mouthpiece?

A mouthpiece is a short tube of length not more than two to three times its diameter, which is. fitted to a tank for measuring the discharge of the flow from the tank. By fitting the mouthpiece, the. discharge through an orifice of the tank can be increased.

What is an convergent-divergent mouthpiece?

If a mouthpiece converges up to vena-contracta and then diverges, this type of mouthpiece is known as a convergent-divergent mouthpiece.
