constraints like tool forces and surface finish. It was found that machining with the MQL set up produced better results in terms of lesser cutting forces and better surface finish in comparison to dry and wet machining.

This provides the necessary water supply and flow measurement facility. Figure 1 shows the arrangement in which the bench supply is led to a vertical pipe terminating in a tapered nozzle. This produces a jet of water which impinges on the vane in the form of a Flat Plate‚ Conical Plate‚ or Hemispherical Cup. The nozzle and vane are contained within a transparent cylinder; at the base of the cylinder there is an outlet by which the flow may be directed to the weighing tank. As indicted in Fig.

almost immediately (don’t try this!). In order for fuel oil to burn‚ it must first be transformed from a liquid to a vaporised state ~ atomised. Atomisation increases the exposure of the fuel to the oxygen in the air; this promotes combustion. A nozzle rated at 0.60 US gallons per hour can generate as many as 50 million droplets of oil in an hour. EFFECTS OF BAD ATOMISING If atomisation is incomplete‚ the droplet sizes are too large for complete combustion. The larger droplets will escape the

competing to develop new machines able to decorate tiles 24 hours-a-day at 30-50 m/min (1000-1500 m2/hour output depending on the resolution). Inkjet decoration machines perfectly fit into glazing lines and improve efficiency. They can have up to 1000 nozzles and work with 6 different inks up to 1000 dpi resolution (for most of tiles 200-300 dpi is sufficient). However‚ the most important feature is the amazing versatility of these devices. Different machines for digital decoration are available with a

The pressure vessel—the engine of the rocket—is usually a used plastic soft drink bottle. The water is forced out by a pressurized gas‚ typically compressed air. The term "aquajet" has been used in parts of Europe in place of the more common "water rocket" and in some places

ice particles from source to nozzle. At that time‚ any ice blockages were attributed to partial melting of ice particles‚ which would favor agglomeration. The use of very cold fluidizing air was deemed absolutely necessary. Periodic system defrosting was required as a result. During this period‚ other methods of ice blast were introduced elsewhere. Gary Settles of Penn State University patented a process in which a cryogenic fluid froze atomized water in a nozzle for blasting. A French version
