WebThe 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 Web) is used to find the Darcy friction factor (f) for the sections of pipe. The value for h L is obtained by diving the pressure drops across the sections of pipe by the product of the density (kg/m3) of the fluid and gravity (m/s2). Using equation 2 below and known values, the friction faction can be calculated. (Eq. 2 ℎ𝐿= 𝑉2 2 Where: h
