CALCULATION OF NPSHA FOR MODELLING PRESSURE CONTROL SYSTEM PREVENTING CAVITATION OF CENTRIFUGAL PUMP SYSTEM

it is well known that cavitation, that occurs when local pressure is lower than vapor, is one of the most problems in centrifugal pump. That might damage pump’s impeller even in a short time which causes financial disaster to pump station. Nowadays many solutions to prevent it by monitoring or using some special sensors which detect cavitation occurrence there are. In this article we examine calculations to the further investigations and constructions of controlling system using several parameters by using flowmeter in Arduino-IDE/MATLAB program based on type of water of Amudarya and Syrdarya.
