Here is how the Head Loss through Screen equation looks like.

2.8431 = 0.0729 \cdot (8^{2} - 5^{2})

2.8431m = 0.0729 \cdot ({8m/s}^{2} - {5m/s}^{2})

2.8431 = 0.0729 \cdot (8^{2} - 5^{2})

Head Loss through Screen Solution

Follow our step by step solution on how to calculate Head Loss through Screen?

FIRST Step Consider the formula

h L = 0.0729 \cdot (v^{2} - u^{2})

Next Step Substitute values of Variables

∴

h L = 0.0729 \cdot ({8m/s}^{2} - {5m/s}^{2})

Next Step Prepare to Evaluate

∴

h L = 0.0729 \cdot (8^{2} - 5^{2})

LAST Step Evaluate

∴

h L = 2.8431m

Formulas to find Head Loss

Velocity of Flow after Screening

The Velocity of Flow after Screening is the flow of water after the screening which depends upon the clear spacing area within the screen.

Symbol: v

Measurement: SpeedUnit: m/s

Note: Value can be positive or negative.

Formulas to find Velocity of Flow after Screening

Velocity of Flow before Screening

The Velocity of Flow before Screening is the flow of water before screening which depends upon the cross-section area of the channel.

Symbol: u

Measurement: SpeedUnit: m/s

Note: Value can be positive or negative.

Formulas to find Velocity of Flow before Screening

Other Formulas to find Head Loss

Go Minimum Head Loss when screen is fully functional

h L = 0.0729 \cdot (v^{2} - u^{2})

Go Maximum Head Loss when screen is 50 percent clogged

h L = 0.0729 \cdot ({(2 \cdot v)}^{2} - u^{2})

Other formulas in Screening category

Go Velocity through Screen given Head Loss through Screen

v = \sqrt{(\frac{h L}{0.0729}) + u^{2}}

Go Velocity above Screen given Head Loss through Screen

u = \sqrt{v^{2} - (\frac{h L}{0.0729})}

How to Evaluate Head Loss through Screen?

Head Loss through Screen evaluator uses Head Loss = 0.0729*(Velocity of Flow after Screening^2-Velocity of Flow before Screening^2) to evaluate the Head Loss, The Head Loss through Screen is a measure of the reduction in the total head of the fluid as it moves through a fluid system. Head Loss is denoted by h_L symbol.

How to evaluate Head Loss through Screen using this online evaluator? To use this online evaluator for Head Loss through Screen, enter Velocity of Flow after Screening (v) & Velocity of Flow before Screening (u) and hit the calculate button.

FAQs on Head Loss through Screen
