Maximum Head Loss when screen is 50 percent clogged Solution

STEP 0: Pre-Calculation Summary

Formula Used

Head Loss = 0.0729*((2*Velocity of Flow after Screening)^2-Velocity of Flow before Screening^2)
h_L = 0.0729*((2*v)^2-u^2)
This formula uses 3 Variables

Variables Used

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.
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.
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.

STEP 1: Convert Input(s) to Base Unit

Velocity of Flow after Screening: 8 Meter per Second --> 8 Meter per Second No Conversion Required
Velocity of Flow before Screening: 5 Meter per Second --> 5 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

h_L = 0.0729*((2*v)^2-u^2) --> 0.0729*((2*8)^2-5^2)

Evaluating ... ...

h_L = 16.8399

STEP 3: Convert Result to Output's Unit

16.8399 Meter --> No Conversion Required

FINAL ANSWER

16.8399 Meter <-- Head Loss

(Calculation completed in 00.004 seconds)

Velocity through Screen given Head Loss through Screen

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

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

Maximum Head Loss when screen is 50 percent clogged

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

Minimum Head Loss when screen is fully functional

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

Head Loss through Screen

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

Maximum Head Loss when screen is 50 percent clogged Formula

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

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.
