Determining Required Water Surface Elevation for Supply Reservoir Using Hazen-Williams Equation

What is the required water surface elevation of the supply reservoir based on the given data?

Can you calculate the required elevation using the Hazen-Williams equation?

Answer:

The required water surface elevation of the supply reservoir should be approximately 5,233.25 feet MSL.

To determine the required water surface elevation of the supply reservoir, we can use the Hazen-Williams equation, which relates flow rate, pipe diameter, pipe material, and hydraulic gradient. The equation is as follows:

Q = (1.318 * C * (D^2.63) * (S^0.54)) / L

Given the flow rate, pipe diameter, and Hazen-Williams coefficient for HDPE pipe, we can calculate the hydraulic gradient and determine the required elevation.

The Hazen-Williams equation is commonly used by engineers to design and analyze water distribution systems. It accounts for factors like pipe material, diameter, and gradient to ensure efficient water flow through pipelines.
