Loss of head due to fluid resistance Solution

STEP 0: Pre-Calculation Summary

Formula Used

Head Loss = Head of the Liquid*(1-(Coefficient of Velocity^2))
h_f = H*(1-(C_v^2))
This formula uses 3 Variables

Variables Used

Head Loss - (Measured in Meter) - Head Loss is a measure of the reduction in the total head (sum of elevation head, velocity head and pressure head) of the fluid as it moves through a fluid system.
Head of the Liquid - (Measured in Meter) - The Head of the liquid is the height of a liquid column that corresponds to a particular pressure exerted by the liquid column from the base of its container.
Coefficient of Velocity - The Coefficient of Velocity is the ratio of actual velocity to theoretical velocity.

STEP 1: Convert Input(s) to Base Unit

Head of the Liquid: 40 Meter --> 40 Meter No Conversion Required
Coefficient of Velocity: 0.92 --> No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h_f = H*(1-(C_v^2)) --> 40*(1-(0.92^2))

Evaluating ... ...

h_f = 6.144

STEP 3: Convert Result to Output's Unit

6.144 Meter --> No Conversion Required

FINAL ANSWER

6.144 Meter <-- Head Loss

Absolute pressure head at constant head and atmospheric pressure head

Go Absolute Pressure Head = Atmospheric Pressure Head+Constant Head-(((Velocity of Liquid Outlet/0.62)^2)*(1/(2*9.81)))

Atmospheric pressure head at constant head and absolute pressure head

Go Atmospheric Pressure Head = Absolute Pressure Head-Constant Head+(((Velocity of Liquid Outlet/0.62)^2)*(1/(2*9.81)))

Loss of head due to sudden enlargement

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

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

Loss of head due to fluid resistance

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

Head of Liquid above Centre of Orifice

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

Loss of head due to fluid resistance Formula

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

What is the co-efficient of velocity?

it is defined as the ratio between the actual velocity of a jet of liquid at the vena-contracta and the theoretical velocity of a jet.

What is fluid resistance?

Fluid resistance is a general term describing the extent to which a rubber product retains its original physical characteristics and ability to function when it is exposed to oil, chemicals, water, organic fluids, or any liquid which it is likely to encounter in actual service.

How to Calculate Loss of head due to fluid resistance?
