# Wastewater Screening Design Calculator

## Water Treatment - Bar Racks and Fine Screens

Solving for discharge coefficient.

#### Inputs:

gravity acceleration (g)
flow rate or discharge through screen (Q)
effective open area (A)

#### Conversions:

= 0
= 0
meter
gravity acceleration (g)
= 0
= 0
meter/second^2
flow rate or discharge through screen (Q)
= 0
= 0
meter^3/second
effective open area (A)
= 0
= 0
meter^2

#### Solution:

discharge coefficient (C)
= NOT CALCULATED
