Area of Cross-section given Proportionate Area Solution

STEP 0: Pre-Calculation Summary

Formula Used

Area of Running Full Sewers = Area of Partially Full Sewers/Proportionate Area
A = a/P_a
This formula uses 3 Variables

Variables Used

Area of Running Full Sewers - (Measured in Square Meter) - The Area of Running Full Sewers refers to the total cross-sectional area of the pipe when it is completely filled with fluid.
Area of Partially Full Sewers - (Measured in Square Meter) - The Area of Partially Full Sewers refers to the cross-sectional flow area at a given water depth, crucial for hydraulic and flow rate calculations.
Proportionate Area - Proportionate Area is ratio of area when water is partially full to area when water is totally full.

STEP 1: Convert Input(s) to Base Unit

Area of Partially Full Sewers: 3.8 Square Meter --> 3.8 Square Meter No Conversion Required
Proportionate Area: 0.703 --> No Conversion Required

What is proportionate area ?

The proportionate area for partially and fully running pipes compares the cross-sectional area of flow when a pipe is not completely full to when it is entirely filled. This ratio helps in analyzing flow characteristics, such as velocity and discharge, under different conditions. It is crucial for designing and assessing the efficiency of drainage and sewer systems, where pipes often operate below full capacity. Understanding this proportion aids in predicting flow behavior and ensuring the system meets design criteria.
