Study a motor pump
Determine characteristic TDH (total dynamic head) graphs against flow rate (for different
wheel diameters, different rotation speeds, suction and load operation)
Define yields (electrical consumption/motor torque/hydraulic power)
Study a self-contained centrifugal pump
Determine the characteristic TDH graph as a function of the flow rate at a set speed
Study of the pump coupling methods
Coupling in series or parallel
Observation of the cavitation
Cavitation due to heating, negative pressure or intake throttling
