An easy-to-use accurate volumetric fuel gauge for use with engine test sets and engines. All connections are made using self-sealing couplings. The couplings ensure the fuel gauge can be connected and disconnected quickly and efficiently with minimum loss or spillage of fuel. The fuel gauge consists of a precision-calibrated two-bulb pipette and control valves. It mounts on the instrumentation frame of the test set and connects between the fuel tank and the engine under test. Students record the time taken to consume a set volume of fuel, from which they can accurately calculate the flow rate.Suitable for use with petrol or diesel. Fuel enters the pipette from the tank. The fuel supply from the tank is then cut off via a valve so that the engine draws fuel from the pipette only.

The measured value of the slope of the graph (dT/dP)SAT obtained from the practical results can be compared with corresponding values calculated from the data in steam tables the German Physicist and one of the founders of Thermodynamics was instrumental in deriving the relevant Clausius-Clapeyron relationship. Marcet Boiler has been developed for investigating the relationship between the pressure and temperature of saturated steam, in equilibrium with water, at all pressures between atmospheric and 17 bar (250 lb/in²).
Features:
Boiler Lagged To Permit Rapid Heating And Arranged For Bench Mounting
Electrically heated boiler fabricated from heavy duty steel section
Supplied complete with safety valve, pressure gauge and water cock
The Marcet Boiler includes a special-purpose glass window. It allows students to see the internal construction of the vessel, to see the boiling process and to check the water level. The electrically-heated boiler holds water. As the water temperature increases, so does the pressure in the boiler. The apparatus consists of a rigid frame containing an insulated pressure vessel and an instrumentation and control unit. The Marcet Boiler is a simple experiment to show the relationship between pressure and temperature for saturated steam for comparison with published results. The frame also has extra space for the optional interface. A digital display shows the values in both SI and traditional units. A transducer and a thermocouple measure the boiler pressure and temperature.

The Mass Oscillations And Hammer Study Unit is provided with a constant level container connected to the water supply by means of a pipe.
In the hydraulic systems the flow variations produce two phenomena: the mass oscillation and the water hammer which are related each other but have different characteristics.
For the water hammer test, the unit is provided with a quick closing valve with manual control in order to obtain an immediate flow interruption.
The oscillation test section is made of stainless steel 3 m long provided with the valves necessary for the flow control and with two pressure measurement devices, the electric signal of which is sent to a double trace memory oscilloscope which allows to examine, in all the phases, the phenomena of mass oscillation.
The Mass Oscillations And Hammer Study Unit is available in two different solutions:
Hydraulic supply from mains
Hydraulic supply from provided with additional tank.
Experiments:
Determination of the transient pressure curve of a water hammer by means of an oscilloscope
Demonstration of the losses in the reservoir and in the balance tank
Water hammer demonstration
Mass oscillation demonstration
Visualization of oscillation characteristics in the balance pipe.
