Coleman fuel is used primarily for fueling lanterns and camp stoves. It is usually sold in one-gallon cans in the United States; [3] in Europe it is usually sold in one-litre bottles. [4] Originally, it was simply casing-head gas or drip gas, which has similar properties. Drip gas was sold commercially at gas stations and hardware stores in ...

A pump stopping; A check valve which closes quickly (i.e., "check valve slam") due to the flow in a pipe reversing direction on loss of motive power, such as a pump stopping. "Non-slam" check valves can be used to reduce the pressure surge.
Centrifugal pumps that are not designed with an internal or external self-priming stage can only start to pump the fluid after the pump has initially been primed with the fluid. Sturdier but slower, their impellers are designed to move liquid, which is far denser than air, leaving them unable to operate when air is present. [ 11 ]
The affinity laws (also known as the "Fan Laws" or "Pump Laws") for pumps/fans are used in hydraulics, hydronics and/or HVAC to express the relationship between variables involved in pump or fan performance (such as head, volumetric flow rate, shaft speed) and power. They apply to pumps, fans, and hydraulic turbines. In these rotary implements ...

In fluid dynamics, total dynamic head (TDH) is the work to be done by a pump, per unit weight, per unit volume of fluid.TDH is the total amount of system pressure, measured in feet, where water can flow through a system before gravity takes over, and is essential for pump specification.
Expander rocket cycle. Expander rocket engine (closed cycle). Heat from the nozzle and combustion chamber powers the fuel and oxidizer pumps. The expander cycle is a power cycle of a bipropellant rocket engine. In this cycle, the fuel is used to cool the engine's combustion chamber, picking up heat and changing phase.
