Flow Rate through Pipe using Manning Formula Solution

STEP 0: Pre-Calculation Summary
Formula Used
Waste water flow = Conveyance factor*(Hydraulic Gradient)^1/2
W = Cf*(i)^1/2
This formula uses 3 Variables
Variables Used
Waste water flow - (Measured in Cubic Meter per Second) - Waste water flow are generated from domestic, industrial, and commercial uses.
Conveyance factor - Conveyance factor is the ratio of the discharge, Q, in a channel to the square root of the energy gradient, Sf.
Hydraulic Gradient - Hydraulic gradient is a specific measurement of liquid pressure above a vertical datum.
STEP 1: Convert Input(s) to Base Unit
Conveyance factor: 20 --> No Conversion Required
Hydraulic Gradient: 2.01 --> No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
W = Cf*(i)^1/2 --> 20*(2.01)^1/2
Evaluating ... ...
W = 20.1
STEP 3: Convert Result to Output's Unit
20.1 Cubic Meter per Second --> No Conversion Required
FINAL ANSWER
20.1 Cubic Meter per Second <-- Waste water flow
(Calculation completed in 00.004 seconds)

Quantity of Sewage Produced Per Day given Sanitary Sewer System Flow Rate
Go Discharge = Sanitary system sewer flow rate/(Area*Population Density of Area)
Population Density given Sanitary Sewer System Flow Rate
Go Population Density of Area = Sanitary system sewer flow rate/(Area*Discharge)
Sanitary Sewer System Flow Rate
Go Sanitary system sewer flow rate = Area*Population Density of Area*Discharge
Manning's Formula for Conveyance Factor given Flow Rate through Pipe
Go Conveyance factor = Waste water flow/sqrt(Hydraulic Gradient)
Fire Demand for Cities of Less than 200,000 Population
Go Fire Demand = 1020*Population in Thousands^0.5*(1-0.01*(Population in Thousands^0.5))
Flow Rate through Pipe using Manning Formula
Go Waste water flow = Conveyance factor*(Hydraulic Gradient)^1/2
Manning's Formula for Pipe Slope given Flow Rate through Pipe
Go Hydraulic Gradient = (Waste water flow/Conveyance factor)^2
Sewer System Length given Total Infiltration to Sanitary Sewer
Go Length = Infiltration/Actual Infiltration
Infiltration given Total Infiltration to Sanitary Sewer
Go Infiltration = Actual Infiltration/Length
Total Infiltration to Sanitary sewer
Go Actual Infiltration = Infiltration*Length
