Uniform flow refers to a fluid flow condition where the velocity and cross-sectional area remain constant along the flow direction, indicating a balance between gravitational forces, friction, and other forces. It is an idealization often used in hydraulic engineering to simplify the analysis of open channel flow and is characterized by steady, parallel streamlines.
Concept
The radius of a pipe is the distance from the center of its cross-section to the inner wall, crucial for determining the pipe's capacity to carry fluid and its hydraulic properties. It directly influences calculations of flow rate, pressure drop, and velocity within the pipe, making it a fundamental parameter in fluid dynamics and engineering design.
Concept
The roughness coefficient is a dimensionless number used in hydraulic engineering to quantify the resistance exerted by a channel surface on the flow of water. It is crucial for calculating flow velocity and discharge in open channels, influencing the design and analysis of hydraulic structures and flood management systems.

Discharge calculation is a vital process in hydrology and environmental engineering that determines the volume of water flowing through a given cross-section of a river or stream per unit time. Accurate discharge measurements are crucial for water resource management, flood prediction, and ecological studies, as they inform decisions on infrastructure development and environmental conservation.
Concept
Subcritical flow occurs in open channel hydraulics when the flow velocity is less than the wave velocity, leading to a tranquil and smooth flow condition. This type of flow is influenced by downstream conditions and is characterized by a Froude number less than one.
