The unit is perfectly self-sufficient, takes up little space and can be easily moved. The hydraulic circuit essentially consists of a high-head centrifugal pump, a flow meter, two pressure gauges theturbine with the transparent end shield, a supply tank and the connecting pipes. An electrically operated centrifugal pump transfers the water under pressure from the main tank to the turbine, simulating thehigh drop and low flowrate conditions as are typical of Pelton turbines. Pelton Turbine Study Unit study unit has been designed for a complete range of tests on Pelton type hydraulic turbines. The purpose of the system is to enable the students to work out the power and torque curves of a Pelton turbine. Next to the nozzle control hand-wheel there is aprofile reproducing the nozzle and the distributor needle on a 1 to 1 scale. A nozzle and a Double needle with hand-wheel control permit the fine adjustment of the turbine supply flow, whilst a jetdiverter makes it possible to prevent exceedingly high runaway velocities.

The apparatus is designed to be used on the working surface of the basic Air Flow Bench and connected by convoluted hose to the 70 mm dia. blown experiment duct on the fan outlet. However, it may be used as a standalone unit by connecting it to any suitable fan with an air supply of approximately 500 litre/sec. at 600 Pascals and by utilising appropriate manometers. A pitot static tube is fitted at the outlet end of the venturi duct and this can be traversed longitudinally along the centre line to enable its measuring tip to be positioned at various points. The apparatus comprises an acrylic duct with the upper and lower surfaces in opaque material and the sides clear. The whole unit forms a 60 x 50 mm rectangular cross section converging to a 20 x 50 mm throat area then diverging back to 60 x 50 mm section at the exit plane. Measured positions are obtained against two scales positioned on opposite sides of the duct to avoid parallax errors. A plot of typical results which can be obtained is shown in the graph. The scales are marked in millimetres but are reversible to show imperial measurements.

The resistance that the spring presents opposite of the elastic deformation is known as spring stiffness. It is a characteristic variable of the spring. In helical springs, the spring force is generated by the elastic deformation of a metal band wound in an Archimedean spiral. If a mass is attached to the spring, we refer to it as a springmass system.
