Hardy Cross Equation, A problem with flow resistance versus electrical resistance makes these electrical analog methods .

Hardy Cross Equation, Select initial pipe sizes (assume a velocity of 3 ft/sec for normal flow with no fire demand). The introduction of the Hardy Cross method for analyzing pipe flow networks revolutionized municipal water supply design. Visualize flow distribution, pressure heads, and convergence. [8] and Ates [9]. With a known/assumed flow and an assumed velocity, use the continuity equation (Q = VA) to calculate the cross-sectional area of flow. His method was the first really useful engineering method in the field of pipe network The method is based on the following basic equations of continuity of flow and head loss that should be satisfied: The Hardy Cross method is a technique for analyzing pipe networks to determine water flow rates at junctions given continuity and energy loss constraints. Try it free! Steps for the Hardy-Cross Method 10. In this example, flow rates, head loss, and pressure at nodes are to be calculated using a spreadsheet. Jan 21, 2026 · Solve complex pipe networks using the Hardy Cross iterative method.
