Series and Parallel Pump Demonstration Unit – Computer Interface
This is a bench top unit for studying the series and parallel pump characteristics with data analysis by computer.
The unit consists of two sets of industrial centrifugal pump and a motor, a PVC storage tank on a steel base, inverter, sensors and software. One pump speed may be varied by advanced inverter while the other pump speed remains normal. By manipulating flow control valves, each pump can be operated individually or both pumps connected in series or parallel. It is to be used with HP 104 Advanced inverter with computer interface unit HP 104 but separately supplied.
Instruction manual is also included.
TYPICAL EXPERIMENTS
- Flow rate vs head at various speeds for one pump.
- Flow rate vs head for two pumps connected in series or parallel.
- Power input, output and overall efficiency at various speeds for one pump.

Hydraulic Studies and AccessoriesOrifice and Jet Flow
This equipment allows determination of coefficient of velocity and coefficient of discharge under various constant heads for two different orifice diameters. Comparison of jet trajectory with that by theory of mechanics can also be made. The equipment is to be used with Hydraulics Bench i.e. HB100 or HB100N (separately supplied).
The equipment consists of a removable clear acrylic cylinder with sharp edge orifice installed at and flush with the lower inside wall of the cylinder. An adjustable overflow allows various constant heads for the test and trajectory of the jet is indicated by probes on the jet path. Heights of the probes are indicated by scales. The apparatus rests on adjustable footings and a level gauge is provided.
TYPICAL EXPERIMENTS- Comparison of the actual and theoretical outlet velocity
- Calculation of discharge coefficient
- Determination of the contraction and velocity coefficients
- Determination of discharge characteristics (jet trajectory) for an orifice mounted in the side of a vertical tank and comparison with simple theory
TECHNICAL DATAOrifice diameter 2 different sizes. Trajectory probes 8, stainless steel Measuring cup 1 L Software for data display and analysis by computer (separately supplied). (0 reviews) -
