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.
If there is a strong thermally driven atmospheric escape of light atoms, heavier atoms can achieve the escape velocity through viscous drag by those escaping lighter atoms. [2] This is another way of thermal escape, called hydrodynamic escape. The heaviest species of atom that can be removed in this manner is called the cross-over mass. [3]

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.
Reports from inside the plane say flight attendants urged people to remain calm and within seconds of the plane coming to a standstill, were able to deploy the escape chutes and usher passengers off.
The evacuation of 379 people on Japan Airlines flight 516 is no casual miracle, but the result of years of work to hone safety procedures and save lives, experts say.
A stepped spillway is a spillway with steps on the spillway chute to assist in the dissipation of the kinetic energy of the descending water. This reduces the need for an additional energy dissipator, such as a body of water, at the end of the spillway downstream.
