WebThe minor loss can be calculated by summarizing the minor loss coefficients - and multiplying the sum with the dynamic pressure head. Total Head Loss in a Single Pipe or Duct. The total head loss for a single pipe can be calculated by using equation (1) and (3): h loss_single = λ (l / d h) (v 2 / 2 g) + Σ ξ v 2 / 2 g (5) WebUse the tables below to calculate Total Dynamic Head (in Feet) required. Use steps 1-3 and the following chart to calculate TDH from tables A & B below. Enter the TDH, in Feet, in the box under “Design Flow Rate” on the Pump Design Guide. Feet 1. Static Head 2. Friction Head: Feet a. Discharge Pipe Length b.
