STEP 0: Pre-Calculation Summary

Formula Used

Flow Velocity = 0.85*Pipe coefficient*(Hydraulic mean depth)^(0.63)*(Bed slope)^(0.54)
V_f = 0.85*C_p*(m)^(0.63)*(s)^(0.54)
This formula uses 4 Variables

Variables Used

Flow Velocity - (Measured in Meter per Second) - Flow Velocity is the velocity of the flow of any fluid.
Pipe coefficient - Pipe coefficient is a constant depend upon pipe dimension.
Hydraulic mean depth - (Measured in Meter) - The Hydraulic mean depth is defined as the area of the flow section divided by the top water surface width.
Bed slope - Bed slope of the sewer under consideration.

STEP 1: Convert Input(s) to Base Unit

Pipe coefficient: 1.2 --> No Conversion Required
Hydraulic mean depth: 10 Meter --> 10 Meter No Conversion Required
Bed slope: 2 --> No Conversion Required
