Surface Elevation Calculation for Water Pipeline
What is the required water surface elevation of the supply reservoir?
Given Length of the pipeline (L) = 2 miles = 10560 ft
Diameter of the pipe (d) = 2.5 ft
Flow rate (Q) = 77.6 cfs
Water temperature (T) = 4°C = 39°F
Water surface elevation of the receiving reservoir (H_r) = 5,280 ft MSL
Answer:
The required water surface elevation of the supply reservoir is 5,286.441 ft MSL.
To determine the water surface elevation of the supply reservoir, the Hazen-Williams equation was used along with various parameters such as the pipeline length, diameter, flow rate, and water temperature. The calculation involved finding the friction factor, head loss, and ultimately the water surface elevation of the supply reservoir.
The flow rate and other specific data were crucial in accurately calculating the required elevation. By considering factors like pipe diameter and length, the equation provided a precise value for the supply reservoir's water surface elevation.
