The Fluid Statics And Pressure Measurement equipment is designed for the study of static fluid and the measurement of pressures with different types of piezometric tubes and level measurement elements as graduated scales and level meter. One of these water columns has atilting system, so that students can clearly see the effect of the different possible inclinations. The tank and the in water columns have graduated scale for immediate and clear display of the water level that can be measured also by the water level supplied with this system. The equipment includes a transparent tank from where it is possible to pour water through valves and pipes and deliver it in the columns installed in the syst

A fan with a flow control valve is connected to the bottom tank, and air is driven upwards through the column and exhausted at the top. Instrument are provided for measurement air flow rate, water flow rate, pressure drop across the cooling tower, temperature and moisture of the inlet and outlet air. This is a Cooling Tower Demonstration Unit. Water is heated in the storage tank, pumped through a flow meter and sprayed at the top of the tower. The water is cooled mainly by evaporation and drops to the bottom tank. Makeup water is admitted to the storage tank through a float valve. The packing in the tower breaks the water into thin films and droplets.
Experiments:
Application of steady flow equation to energy balance.
Cooling tower performance at various air and water flow rates with different inlet water temperatures.
Observation of water flow patterns and distribution.
Measurement of water and air flow rates, temperatures and humidity.
Function of the RSF governor
Function of the pressure valves
Displacement of the piston rod
Torsion of all pump plungers
By turning the camshaft one can see thestroke of all pump plungers.
