Cutaway of Space Shuttle external tank. Autogenous pressurization is the use of self-generated gaseous propellant to pressurize liquid propellant in rockets.Traditional liquid-propellant rockets have been most often pressurized with other gases, such as helium, which necessitates carrying the pressurant tanks along with the plumbing and control system to use it.
This is the process by which atmospheric pressure is maintained in an isolated or semi-isolated atmospheric environment (for instance, in an aircraft, [1] or whilst scuba diving). See also [ edit ]
Gas Pressure: 25 bars The turbopump is controlled by an electronic controller which measures outlet pressure and RPM, adjusting H 2 O 2 flow as necessary. Each of the two turbine & pump units have a gas generator, and the units are mounted back to back but rotate in opposite directions and at different speeds.
A squeeze bottle is a type of container such as a plastic bottle for dispensing a fluid, that is powered by squeezing the container by exerting pressure with the user's hand. Its fundamental characteristic is that manual pressure applied to a resilient hollow body is harnessed to compress fluid within it and thereby expel the fluid through some ...

A Bridgman seal, invented by and named after Percy Williams Bridgman, can be used to seal a pressure chamber and compress its contents to high pressures (up to 40,000 MPa), without the seal leaking and releasing the pressure [1] [2] The top is outside the pressure vessel; the bottom is inside. The topmost cylinder is the drive piston; it has an ...
Plan or attend holiday events where alcohol isn’t the main attraction “Parties are often centered around alcohol,” says Dr. Stephen Holtsford, medical director at Recovery Centers of America .
A pressure exchanger transfers pressure energy from a high pressure fluid stream to a low pressure fluid stream. Many industrial processes operate at elevated pressures and have high pressure waste streams. One way of providing a high pressure fluid to such a process is to transfer the waste pressure to a low pressure stream using a pressure ...
