The gas-lift mandrel is a device installed in the tubing string of a gas-lift well onto which or into which a gas-lift valve is fitted. There are two common types of mandrels. In a conventional gas-lift mandrel, a gas-lift valve is installed as the tubing is placed in the well. Thus, to replace or repair the valve, the tubing string must be pulled.
Petroleum production engineers design and select subsurface equipment to produce oil and gas well fluids. [1] They often are degreed as petroleum engineers, although they may come from other technical disciplines (e.g., mechanical engineering, chemical engineering, physicist) and subsequently be trained by an oil and gas company.
In aeronautics, a spoiler (sometimes called a lift spoiler or lift dumper) is a device which intentionally reduces the lift component of an airfoil in a controlled way. Most often, spoilers are plates on the top surface of a wing that can be extended upward into the airflow to spoil the streamline flow.
The Mist lift, Mist flow or Steam lift pump is a gas lift technique of lifting water used in a form of Ocean Thermal Energy Conversion (OTEC) where water falls to operate a hydro-electric turbine. The water is pumped from the level it drops to using rising steam which is combined into a multiphase flow. [ 1 ]
In fact, the air moving over the top of an aerofoil generating lift is always moving much faster than the equal transit theory would imply, as described in the incorrect and correct explanations of lift force. Blowing over a curved piece of paper does not demonstrate Bernoulli's principle. Although a common classroom experiment is often ...

Ernst, who chairs the Senate DOGE caucus, claimed in the report that just 6% of federal workers actually work in-person full-time. That 94% segment is who Musk and Ramaswamy are zeroing in on.
A gas lift chair is a form of office chair that allows the user to modify their height in relation to the height of a desk, leading to an increase in comfort and ergonomic benefit. A patent describing a common configuration of a gas lift cylinder by John Wang, published 20 May 1989.
