1D Pumps: Difference between revisions

Once you have your manufacturer curve for your given pump it is now necessary to create the curve .csv for TUFLOW to read in. The manufacturer specifications will need to be translated into a total head vs pump rate chart. Although reading in the depth discharge database is the same process as other boundary conditions within TUFLOW, the curve itself is fundamentally different as you no longer need to start the csv file with 0,0. If the curve did start at 0,0 this would not make sense because at a total head difference of 0m the pump should effectively be operating at peak performance so the flow rate would be greater than 0 m3. This is why builds prior to 2015 cannot be used with pump curves as it still requires csv dbase entries to start at 0,0. The image below shows a csv file for the pump performance curve given in the previous section. <br>
