   A demonstration of a fire escape chute on the streets of Daegu, South Korea. An escape chute is a special kind of emergency exit, used where conventional fire escape stairways are impractical. The chute is a fabric (or occasionally metal) tube installed near a special exit on an upper floor or roof of a building, or a tall structure.

   The MES consists of five components. Controls – used to initiate the device in an emergency situation. [9]Stowage box – contains essentials for the evacuation, including the chute and the fixed appliances, such as seats, rails, etc. [10] Composed of marine grade aluminum along with inflation cylinders, usually kept on the deck taking as little as 4 m 2 of storage space.

4. Open channel spillway - Wikipedia

   en.wikipedia.org/wiki/Open_channel_spillway

   There are four main components of a chute spillway: [1] The elements of a spillway are the inlet, the vertical curve section (ogee curve), the steep-sloped channel and the outlet. In order to avoid a hydraulic jump , the slope of the spillway must be steep enough for the flow to remain supercritical.

7. Effusion - Wikipedia

   In physics and chemistry, effusion is the process in which a gas escapes from a container through a hole of diameter considerably smaller than the mean free path of the molecules. [1] Such a hole is often described as a pinhole and the escape of the gas is due to the pressure difference between the container and the exterior.

9. Graham's law - Wikipedia

   en.wikipedia.org/wiki/Graham's_law

   Thus, if the molecular weight of one gas is four times that of another, it would diffuse through a porous plug or escape through a small pinhole in a vessel at half the rate of the other (heavier gases diffuse more slowly). A complete theoretical explanation of Graham's law was provided years later by the kinetic theory of gases.
