Feb 2, 2011 · The term flashing flow is reserved for the flow with dramatic evaporation of liquid due to a drop of pressure P. The process of production of the vapor phase is usually accompanied by massive thermodynamic and mechanical nonequilibrium by virtue of a difference in temperature and velocity of both phases. The rate of evaporation in a fluid ...

When you empty water from a plastic bottle, you've probably noticed you can do it in two very differentways. If you tip the bottle at a shallow angle, the water comesout very smoothly; air moves past it, in the opposite direction,filling the bottle with "emptiness." If you tip the bottle more,or hold it vertically, the water comes out noisily, in j...
The speed at which a fluid flows past an object varies according to how far from the object you are. Ifyou're sitting in a parked car and a gale-force wind is howling pastyou at 200km/h (125mph), you might think the difference in speed between theair and the car is 200km/h—and it is! But there's not a sudden,drastic discontinuity between the statio...
Photo: The faster you go, the harder you have to work against the air. Air resistance doesn't really matter when you walk, because you're not traveling fast enough. But if you cycle, you need to think about aerodynamics much more and adopt a streamlined posture that disturbs the airflow as little as possible. Like this rider, you might want to get ...
In engineering, airflow is a measurement of the amount of air per unit of time that flows through a particular device. It can be described as a volumetric flow rate (volume of air per unit time) or a mass flow rate (mass of air per unit time).
In simplest terms, air needs an opening or hole to flow through and driving force to move it. Many different factors control how air flow affects a house. This section examines the forces and conditions that allow air to flow into, out of, or within a building, including: Controlled versus uncontrolled airflow.
The air flow behind the fan is slow moving and wide (you can see the arrows behind the fan coming from above and below the fan blades) whereas the air flow in front of the fan is fast moving and narrow (which follows from the conservation of mass flow.

May 15, 2019 · Volume. Standard air is air that is 70ºF with 50% RH, at sea level. We measure air volume as a rate in cubic feet per minute (cfm). 1 ft3 of standard air weighs .0741 pounds. 13.33 ft3 = 1 pound of air. 13.33 cubic feet of air is about the amount of air in a typical residential refrigerator. .244 is the Specific Heat of air.
