  Pitot-Static Tube Apparatus

  It is possible to move the Pitot-static tube across the entire cross-section of the pipe and thus measure the pressure profile. The position of the measuring tip relative to the bottom of the pipe can be read on a scale. The Pitot-static tube can be connected to any differential pressure manometer using hose connections. Differential pressures up to approx. 50mbar are possible when using the pump .The water supply is provided either from the laboratory mains or using the (closed water circuit).

  Demonstration Pelton Turbine

  A characteristic of impulse turbines is the complete conversion of pressure into kinetic energy at the exit of the supply nozzle. The turbine consists of a housing, which is transparent on one side, the Pelton bucket wheel and an adjustable supply nozzle. The turbine is loaded with a belt brake. The torque is measured using spring balances located on the braking belt. The manometer fitted to the unit measures the water pressure applied. The pressurised water supply and flow rate measurement is provided . Alternatively, the arrangement can also be operated from the laboratory mains supply.

  Pipe Network Bench

  A common problem in the installation of pipe-work is the determination of pressure and flow rate in complex pipe systems. The Pipe Network Bench facilitates the setting up and investigation of different types of pipe system, for instance series and parallel configurations of pipes, their branches and joints. Analogous to Kirchoff’s laws in electrical engineering, the pressure in the pipes corresponds to the electrical voltage, the pressure losses to the electrical resistances. Node analyses can be performed. The pipe systems can be assembled on the top of the experimental module using the pipes and connecting fittings supplied. The experimental module includes a closed water circuit with supply tank and pump, and a tank for volumetric flow rate measurement. Two-tube manometers with different measuring ranges are included for pressure measurements.
