Velocity above Screen given Head Loss through Screen Solution

STEP 0: Pre-Calculation Summary

Formula Used

Velocity of Flow before Screening = sqrt(Velocity of Flow after Screening^2-(Head Loss/0.0729))
u = sqrt(v^2-(h_L/0.0729))
This formula uses 1 Functions, 3 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 Flow before Screening - (Measured in Meter per Second) - The Velocity of Flow before Screening is the flow of water before screening which depends upon the cross-section area of the channel.
Velocity of Flow after Screening - (Measured in Meter per Second) - The Velocity of Flow after Screening is the flow of water after the screening which depends upon the clear spacing area within the screen.
Head Loss - (Measured in Meter) - The 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.

STEP 1: Convert Input(s) to Base Unit

Velocity of Flow after Screening: 8 Meter per Second --> 8 Meter per Second No Conversion Required
Head Loss: 2.84 Meter --> 2.84 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

u = sqrt(v^2-(h_L/0.0729)) --> sqrt(8^2-(2.84/0.0729))

Evaluating ... ...

u = 5.00425059379394

STEP 3: Convert Result to Output's Unit

5.00425059379394 Meter per Second --> No Conversion Required

FINAL ANSWER

5.00425059379394 ≈ 5.004251 Meter per Second <-- Velocity of Flow before Screening

(Calculation completed in 00.020 seconds)

Velocity through Screen given Head Loss through Screen

LaTeX Go Velocity of Flow after Screening = sqrt((Head Loss/0.0729)+Velocity of Flow before Screening^2)

Velocity above Screen given Head Loss through Screen

LaTeX Go Velocity of Flow before Screening = sqrt(Velocity of Flow after Screening^2-(Head Loss/0.0729))

Minimum Head Loss when screen is fully functional

LaTeX Go Head Loss = 0.0729*(Velocity of Flow after Screening^2-Velocity of Flow before Screening^2)

Head Loss through Screen

LaTeX Go Head Loss = 0.0729*(Velocity of Flow after Screening^2-Velocity of Flow before Screening^2)

Velocity above Screen given Head Loss through Screen Formula

LaTeX Go

Velocity of Flow before Screening = sqrt(Velocity of Flow after Screening^2-(Head Loss/0.0729))
u = sqrt(v^2-(h_L/0.0729))

What is head loss?

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 loss is unavoidable in real fluids.

Why is screening done in WTP (Water Treatment Plant)?

Screening is done to remove floating materials from the raw water. There are 2 types of screen
1. Coarse Screen- clear spacing between the bar is 20-100mm.
2. Fine Screen- clear spacing in the mesh is <1mm.
Screens are provided to protect
i. pumps
ii. valves
iii. pipeline and other appurtenance from damage or clogging by rags and other large objects.

How to Calculate Velocity above Screen given Head Loss through Screen?
