easily be identified with the Darcy-Weisbach equation g V D L h f 2 2 where ? is a function of relative roughness k s /D and Reynolds number Re, a function given (Topic 2) by the Colebrook-White equation. Hydraulics 2 T3-8 David Apsley Example. The drag force on a body in a fluid flow is a function of the body size (expressed via a characteristic length L) and the fluid velocity V, density ?... The Energy Equation In addition to pressure head, elevation head, and velocity head, energy may be added to a system by a pump (for example), and removed from the system by friction or other

The Mathematics of Pumping Water Therefore , equation (1) becomes: Total s D H = H + H … (2) The static head s H is the physical change in elevation between the surface of the reservoir and the point of discharge into the receiving tank. As the water level in the reservoir can vary, the static head for the system will vary between a maximum and a minimum value: discharge level reservoir

- Spreadsheets for Pipe Flow-Friction Factor Calculations Harlan H. Bengtson, PhD, P.E. COURSE CONTENT 1. Introduction Several kinds of pipe flow calculations can be made with the Darcy- Weisbach equation and the Moody friction factor. Many of the calculations require an iterative solution, so they are especially suitable for an Excel spreadsheet solution. This course includes discussion of …
- For derivation and discussion of the Darcy-Weisbach relation, and the discussion below, see Henderson, 1966. In this paper 1/!! is called the Darcy-Weisbach factor. The Manning’s roughness can be calculated from the Darcy-Weisbach factor using the equation: !=!!!!/ 8! 1 1/! The unknown in the equation is 1/!!!.! The equation for 1/!! is based on the original experiments of Nikuradse and is
- Brinkman's equation reverts to Darcy's equation for flow in porous media, since the last term then normally is negligible, and to Stoke's equation for channel flow because the Darcy part of the equation then may be neglected.
