• Size or evaluate flow for sharp-crested weirs , broad-crested weirs , and orifices <br /> • FlowMaster can now calculate parabolic channels , box pipes , and elliptical pipes <br /> • FlowMaster will solve for any variable, including discharge , headwater elevation , <br /> discharge coefficient and more . Even submergence (tailwater effect) in orifices and <br /> weirs is taken into account <br /> • Enter the geometry and variable roughness for your irregular sections (open or <br /> closed ) to model irregular open and closed cross sections effortlessly <br /> • Compute composite roughness values for your irregular section using various <br /> methods including Lotter, Horton , Pavlovskii, or the Colebatch and Cox method , as <br /> well as the combination of Horton and Lotter that was available in the previous <br /> version <br /> • Model ditches and swoles regardless of size and shape . Geometric shapes include <br /> circular, rectangular, trapezoidal , triangular, gutter, and irregular <br /> • Perform a quick check or a design on a pressure pipe by simply plugging in the <br /> ' known information and clicking to solve for the unknown <br /> • Change friction methods from each individual worksheet on-the-fly, allowing you to <br /> compare the results using any method <br /> u <br /> ... . .. <br /> .....:.rte <br /> i <br /> FlowMaster Interface FlowMaster Analysis and Design <br /> StormCAD <br /> StormCAD offers a complete approach to storm sewer design and analysis, from rainfall to <br /> outlet . <br /> " • StormCAD makes if easy to model stormwater systems with : <br /> • Gradually varied flow computations <br /> • IMPROVED !
