Frequently asked questions
What is the Reynolds number?
The Reynolds number is a dimensionless ratio of inertial to viscous forces that helps predict whether flow is laminar or turbulent.
What is the Moody diagram used for?
The Moody diagram gives the friction factor for flow in a pipe as a function of Reynolds number and relative roughness, so engineers can estimate pressure loss.
What is computational fluid dynamics?
Computational fluid dynamics (CFD) uses numerical methods to simulate fluid flow and its interaction with surfaces, and is widely used in engineering design and research.
What does a relief valve do?
A relief valve opens at a set pressure to release fluid, which keeps pressure vessels and other equipment from exceeding their pressure limits.
