Indoor fire hose with a fire extinguisher. A fire hose (or firehose) is a high-pressure hose that carries water or other fire retardant (such as foam) to a fire to extinguish it. Outdoors, it attaches either to a fire engine, fire hydrant, or a portable fire pump. [1] Indoors, it can permanently attach to a building's standpipe or plumbing system.
The substantial redesign of the engine included an all-new cylinder head with reshaped combustion chambers and inlet ports for 'lean-burn' operation, hardened valve seats and valves for operation on unleaded fuel, and the Ford EDIS fully electronic ignition system, with the option of single-point fuel injection for use with a catalytic ...
The closed loop system can be more effective cooling the air (during air temperature extremes) than an open system, since it cools and recools the same air. Open system: Outside air is drawn from a filtered air intake (Minimum Efficiency Reporting Value MERV 8+ air filter is recommended) to cool or preheat the air. The tubes are typically 30 m ...
Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. [1] A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [2]
Earlier versions of this engine also used a single port fuel injection system Honda called PGM-CARB, signifying the carburetor was computer controlled. D12 series engines (1.2 liter) [ edit ]
Reverse osmosis (RO) is a water purification process that uses a semi-permeable membrane to separate water molecules from other substances. RO applies pressure to overcome osmotic pressure that favors even distributions.
