Urroz, October 2005, 18 pgs. 1. Darcy-Weisbach Equation and friction factor Function DARCY in HP calculators The HP 48G and HP 49G series calculators provide function DARCY(ee/D,R)1 to calculate the friction factor ƒ for turbulent flows. In the HP 48G, function DARCY is available … Equations for the friction factor Implementing Haaland’s and Swamee-Jain equations … 2. Types of problems involving the Darcy-Weisbach equation for friction losses Solution of sample problems using the Moody diagram Solution using functions DARCY, ƒHA and ƒSJ instead of the Moody diagram 3. Combining the Darcy-Weisbach equation with various equations for ƒ Darcy-Weisbach and Haaland equations Darcy-Weisbach and Swamee-Jain equations Solution of sample problems using equations … DWCWQ: DWHAQ: DWSJQ: Solution with HP calculators 4 - Numerical solution of friction problems using functions DARCY, ƒHA and ƒSJ Solving friction loss problems in terms of flow discharge 5 – Empirical equations for single-pipe flow The Hazen-Williams equation The Manning’s equation Non-rigorous head-loss equations Comprehensive with illustrations, equations, formulas, programs, examples etc. BEST!
