JORGE ORTEGA Posted August 5, 2020 Report Share Posted August 5, 2020 My question Is about the NPSHa, because PUMPSIM does not consider the atmospheric pressure in that calculation... It's that correct? Regards Quote Link to comment Share on other sites More sharing options...
Martin Griffith Posted August 7, 2020 Report Share Posted August 7, 2020 Hi Jorge, thanks for your question. Pumpsim does include the atmospheric pressure in the NPSH calculation. The atmospheric pressure is configurable in Settings | Simulation | Environment | Surface Pressure Barometric. The default value is 1.01 bar. You can change this value and this will affect the pump NPSH checks. Quote Link to comment Share on other sites More sharing options...
