Description
solution for this problem.
Water in steady state flows through the 8-pipe network shown below. The flow rates, pipe information and node elevations are given in the information table. Use the Hardy Cross approach to analyze the network and complete the table. The initial flow rate of pipe #1 in ft3/sec is: Q1 = (y + 30,000) / 100,000, where: y = your GMU student ID number, with the “G” and leading zeros removed. Round your Q1calculation to two decimal places. To receive credit for this assignment you must attach all of your calculations with the completed table. If you use a spreadsheet, upload your spreadsheet model.
