Absolute pressure head at constant head and atmospheric pressure head Solution

STEP 0: Pre-Calculation Summary

Formula Used

Absolute Pressure Head = Atmospheric Pressure Head+Constant Head-(((Velocity of Liquid Outlet/0.62)^2)*(1/(2*9.81)))
H_AP = H_a+H_c-(((V_o/0.62)^2)*(1/(2*9.81)))
This formula uses 4 Variables

Variables Used

Absolute Pressure Head - (Measured in Meter) - The Absolute Pressure Head is considered for the liquid at venacontracta.
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.
Velocity of Liquid Outlet - (Measured in Meter per Second) - The Velocity of liquid outlet is considered on flow through an external cylindrical mouthpiece.

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
Velocity of Liquid Outlet: 5.5 Meter per Second --> 5.5 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

H_AP = H_a+H_c-(((V_o/0.62)^2)*(1/(2*9.81))) --> 7+10.5-(((5.5/0.62)^2)*(1/(2*9.81)))

Evaluating ... ...

H_AP = 13.4890892620561

STEP 3: Convert Result to Output's Unit

13.4890892620561 Meter --> No Conversion Required

FINAL ANSWER

13.4890892620561 ≈ 13.48909 Meter <-- Absolute Pressure Head

Loss of head due to sudden enlargement

LaTeX Go Loss of Head = ((Velocity of Liquid Inlet-Velocity of Liquid Outlet)^2)/(2*9.81)

Head of liquid for head loss and coefficient of velocity

LaTeX Go Head of the Liquid = Head Loss/(1-(Coefficient of Velocity^2))

Loss of head due to fluid resistance

LaTeX Go Head Loss = Head of the Liquid*(1-(Coefficient of Velocity^2))

Head of Liquid above Centre of Orifice

LaTeX Go Head of the Liquid = (Theoretical Velocity^2)/(2*9.81)

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 external cylindrical mouthpiece?

The mouthpiece is an attachment in the form of a small tube fixed to an orifice. When the tube is fixed externally, it is known as an external mouthpiece. Depending on the shape, a mouthpiece can be cylindrical, convergent, divergent, convergent-divergent, or of any other form.
