Thread Content
Project, Medium density, Operating pressure inside the container (absolute pressure), Saturated vapor pressure under medium operating conditions (absolute pressure), Height from the liquid surface to the center of the impeller, Resistance loss in the inlet pipeline, Unit: Kg/m3, KPa, KPa, m, m. Values: 581.1, 1380, 410, 0, 0. Cavitation head (m): 170.16
The required net positive suction head must be created; it cannot be calculated； The effective net positive suction head is related to the outlet piping and needs to be calculated.
