Fluid flow through valves
– Investigate pressure drop by comparing flow through a straight pipe compared to flow through a valve [or valves of various sizes]
Fluid flow through pipes
– Investigate pressure drop by comparing flow through a straight pipe compared to flow through a pipe of equal length but with elbows and tee fittings
Flow of fluid of different viscosity
. Investigate the difference in flow of fluids of low and high viscosity [runniness]. For example: Water [as a base], light oil, heavy oil, treakle /golden syrup.
Fluid viscosity related to temperature. Investigate the viscosity [‘runniness’] change in a fluid when the temperature changes.
Flow of fluid related to pressure
. Investigate the effect of fluid flow under various pressures through pipes.
Effect of fluids on various materials
. Investigate how common industrial seal materials react to various fluids.
. Investigate how electrical energy can be converted into mechanical energy. [An electro magnet or solenoid]. Build a simple one.
Investigate solenoid coils of different wattages [power] providing differing amounts of mechanical energy. [More electrical power = more mechanical ‘push’]
Investigate the effect on electrical current draw [in Amps] for various Power [in Watts] DC voltage coils. This is just the Watts = DC Volts x Amps equation.
Investigate the effect on the resistance of a solenoid coil as the temperature changes.
Investigate the effect of AC voltage [as opposed to DC] on a solenoid or electromagnet. This could include
This is not a complete set of suggestions – there are more possibilities. We [ODENZ] could help with advice and some materials to enable the above experiments to be put into practice.
