    The pressure that is required to do so is equal and opposite to the water potential of the sample (Ψ leaf or Ψ total). [1] [2] Pressure bombs are field portable and mechanically simple, [3] which make them the predominant method for water potential measurements in the fields of plant physiology and ecophysiology.

    en.wikipedia.org/wiki/Portable_hyperbaric_bag

    Medical students demonstrate the use of a portable hyperbaric bag. A portable hyperbaric bag, of which one brand is the Gamow (pronounced) bag, is an inflatable pressure bag large enough to accommodate a person. The patient can be placed inside the bag, which is then sealed and inflated with a foot pump.

  4. Titanium sublimation pump - Wikipedia

    en.wikipedia.org/wiki/Titanium_sublimation_pump

    Since clean titanium is very reactive, components of the residual gas in the chamber which collide with the chamber wall are likely to react and to form a stable, solid product. Thus the gas pressure in the chamber is reduced. [1] After some time, the titanium film will no longer be clean and hence the effectiveness of the pump is reduced.

  5. Pistonless pump - Wikipedia

    en.wikipedia.org/wiki/Pistonless_pump

    For each half of the pump system, a chamber is filled from the main tank under low pressure and at a high flow rate, then the chamber is pressurized, and then the fluid is delivered to the engine at a moderate flow rate under high pressure. The chamber is then vented and cycle repeats. The system is designed so that the inlet flow rate is ...

  6. Hand pump - Wikipedia

    en.wikipedia.org/wiki/Hand_pump

    Hand-powered force pump, with an air chamber to smooth out variations in flow rate. Hand pumps are manually operated pumps; they use human power and mechanical advantage to move fluids or air from one place to another. They are widely used in every country in the world for a variety of industrial, marine, irrigation and leisure activities.

  7. Turbopump - Wikipedia

    en.wikipedia.org/wiki/Turbopump

    A turbopump is a propellant pump with two main components: a rotodynamic pump and a driving gas turbine, usually both mounted on the same shaft, or sometimes geared together. They were initially developed in Germany in the early 1940s. The purpose of a turbopump is to produce a high-pressure fluid for feeding a combustion chamber or other use ...
