2. Dilution refrigerator - Wikipedia

   en.wikipedia.org/wiki/Dilution_refrigerator

   Pulse tube coolers are commonly used cryocoolers in dry dilution refrigerators. Dry dilution refrigerators generally follow one of two designs. One design incorporates an inner vacuum can, which is used to initially precool the machine from room temperature down to the base temperature of the pulse tube cooler (using heat-exchange gas).

3. Torricelli's experiment - Wikipedia

   en.wikipedia.org/wiki/Torricelli's_experiment

   The experiment uses a simple barometer to measure the pressure of air, filling it with mercury up until 75% of the tube. Any air bubbles in the tube must be removed by inverting several times. After that, a clean mercury is filled once again until the tube is completely full. The barometer is then placed inverted on the dish full of mercury.

4. Recuperative multi-tube cooler - Wikipedia

   en.wikipedia.org/wiki/Recuperative_multi-tube_cooler

   Recuperative multi-tube coolers essentially exist of a turning rotor which is mostly driven via chain. At the ends of the rotor are stiff cases for product feed and outlet. The rotor is supported on running treads, as it is typical for rotary drums. The interior of the rotor exists of several tubes in a revolvertype (or planetary) arrangement.

5. Tubing (recreation) - Wikipedia

   Related to kite tubing is the kited inflated wing, a stiffened, flexible wing or gas-inflated bladder wing, where a control bar is affixed for the kited person to direct the inflated wing so the dangerous lock-out does not occur. The kited person can have a quick disconnect to release from a towing boat or car if a dangerous angle of tow begins.

   Figure 2: Left: (near X 2): a gas element enters the tube with temperature T L and leaves it with a lower temperature. Right: (near X 3): a gas element enters the tube with temperature T H and leaves it with a higher temperature. The part in between X 1 and X 3 is thermally insulated from the surroundings, usually by vacuum. The pressure varies ...
