Minimum Head Loss when screen is fully functional Solution

STEP 0: Pre-Calculation Summary

Formula Used

Head Loss = 0.0729*(Velocity of Flow after Screening^2-Velocity of Flow before Screening^2)
h_L = 0.0729*(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*(v^2-u^2) --> 0.0729*(8^2-5^2)

Evaluating ... ...

h_L = 2.8431

STEP 3: Convert Result to Output's Unit

2.8431 Meter --> No Conversion Required

FINAL ANSWER

2.8431 Meter <-- Head Loss

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.

FAQ

What is Minimum Head Loss when screen is fully functional?

The Minimum Head Loss when screen is fully functional is defined as the Head Loss through Screen, which measures the reduction in the total head of the fluid as it moves through a fluid system and is represented as h_L = 0.0729*(v^2-u^2) or Head Loss = 0.0729*(Velocity of Flow after Screening^2-Velocity of Flow before Screening^2). The Velocity of Flow after Screening is the flow of water after the screening which depends upon the clear spacing area within the screen & The Velocity of Flow before Screening is the flow of water before screening which depends upon the cross-section area of the channel.

How to calculate Minimum Head Loss when screen is fully functional?

The Minimum Head Loss when screen is fully functional is defined as the Head Loss through Screen, which measures the reduction in the total head of the fluid as it moves through a fluid system is calculated using Head Loss = 0.0729*(Velocity of Flow after Screening^2-Velocity of Flow before Screening^2). To calculate Minimum Head Loss when screen is fully functional, you need Velocity of Flow after Screening (v) & Velocity of Flow before Screening (u). With our tool, you need to enter the respective value for Velocity of Flow after Screening & Velocity of Flow before Screening and hit the calculate button. You can also select the units (if any) for Input(s) and the Output as well.

How many ways are there to calculate Head Loss?

In this formula, Head Loss uses Velocity of Flow after Screening & Velocity of Flow before Screening. We can use 2 other way(s) to calculate the same, which is/are as follows -

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