20. Flow Control Valves

20. Flow Control Valves

The chapter focuses on fluid mechanics, particularly on understanding flow control through various types of valves and the application of mass conservation, energy loss, and Bernoulli’s equation in pipe flow systems. Key aspects include managing flow energy losses due to different fittings and configurations and applying these principles to real-world fluid systems effectively.

Key Concepts

-- Bernoulli's Equation
An equation that relates pressure, velocity, and height in a flowing fluid, incorporating energy losses in system designs.
-- Energy Loss Coefficient (K)
A value that quantifies the energy losses in a system due to fittings and configurations in fluid flow, affecting system efficiency.
-- Control Volume
A defined region in fluid mechanics used to analyze the mass and energy transfer across its boundaries.
-- Reynolds Number (Re)
A dimensionless quantity that helps predict flow patterns in different fluid flow situations, determining whether flow is laminar or turbulent.
-- Hydraulic Gradient
A line representing the energy head of water flows, showing the relationship between the pressure head, elevation head, and velocity head at different points in a system.
