computations. A key element is that all three components will use a common geometric data representation and common geometric and hydraulic computation routines. In addition to the three hydraulic analysis components, the system contains several hydraulic design features that can be invoked once the basic water surface profiles are computed.

Hydrologic Modeling System HEC-HMS

The Hydrologic Modeling System (HEC-HMS) is designed to simulate the precipitation-runoff processes of dendritic watershed systems. It supercedes HEC-1 and provides a similar variety of options but represents a significant advancement in

Pipe Flow/Friction Factor Calculations using Excel ...

The Darcy-Weisbach equation or the Fanning equation and the friction factor (Moody friction factor or Fanning friction factor) are used for a variety of pressure pipe flow calculations. Many of these types of calculations require a graphical and/or iterative solution. The necessary iterative calculations can be carried out conveniently through the

CE-092 Pipe Flow-Friction Factor Calculation

Pipe Flow-Friction Factor Calculations with Excel 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.
