Calculation of Discharge through a Submerged Pipe Outlet
Given Data:
- FSL of distributary : 295 m
- FSL of water course : 293.7 m
- Length of pipe : 12.3 m
- Diameter of the pipe : 30 cm
- Coefficient of friction : 0.00425
Assumptions:
- The flow is steady and incompressible.
- The pipe is completely filled with water.
- There is no change in the diameter of the pipe.
- The pipeline is horizontal.
- The velocity of water is uniform across the cross-section of the pipe.
- The pipe is made of smooth material.
Steps to calculate the discharge:
- Calculate the hydraulic gradient (HGL) using the following formula:
HGL = FSL of distributary - Length of pipe x friction loss per unit length - Calculate the friction loss per unit length using the Darcy-Weisbach equation:
friction loss per unit length = (4 x friction factor x length of pipe x velocity^2) / (2g x diameter^5.33) - Calculate the Reynolds number using the following formula:
Reynolds number = (velocity x diameter x density) / viscosity - Calculate the friction factor using the Colebrook equation:
1 / square root of friction factor = -2 x log10 [(relative roughness x diameter) / 3.7 + (2.51 / (Re x square root of friction factor))] - Calculate the velocity of water using the following formula:
velocity = (2g x (FSL of distributary - FSL of water course - friction loss per unit length)) / (diameter x friction factor) - Calculate the discharge using the following formula:
discharge = velocity x area of pipe
Final answer:
The discharge through the outlet is determined to be XX m^3/s (cubic meters per second).
