The engine flameout condition occurs when the combustion process within the combustor has stopped working.The Exhaust Gas Temperature (EGT), an important performance parameter, drops, forcing the engine pressure ratio and core speed (N2) to drop. The flameout condition may occur for various reasons...
Melting occurs when heat is applied to a solid. The solid matter's particles start to vibrate rapidly and move apart from each other. This process increases the distance between them. Once specific temperature and pressure conditions are achieved, the solid transforms into a liquid. This specific...
sulphur and a handful of other substances). The majority of the carbon found in coal is bound, meaning there is one C-C bond to every C atom. Energy release occurs when a C-C bond is broken. Roughly 43g of carbon dioxide is
low-pressure gas that comes out of the freezer compartment and pumping it into a separate area until the gas is compressed and once again under high pressure. The compression of the gas causes an increase in temperature. When done, the gas is allowed to escape from the compressor and eventua...
A gasket is a specific mechanical component typically made from materials such as rubber, metal, or composites. It is designed to fill gaps between two mating surfaces, creating a tight seal when compressed. Gaskets are generally used in static situations where the sealed parts do not move signi...
Heat pumping occurs when a hot object is brought into contact with a cold object. The heat will flow from the hot object to the cold object and never spontaneously reverse. The heat between the two objects will even out until they are the same. The heat was pumped from the hot to the...
A heat dome occurs when hot ocean air is trapped over a large area. High atmospheric pressure over the region pushes air down, causing it to heat up as it is compressed. This action causes the formation of a “lid” or “cap” that seals heat in the area and traps heat in the dome...
of a gas without allowing any exchange of heat with the surroundings. Adiabatic cooling occurs when air rises or when a parcel of air is cooled as it expands through isentropic lifting. Adiabatic heating occurs when air sinks or a parcel is compressed as it is isentropically compressed. ...
What is the difference between a restrictive and an obstructive pulmonary condition? Maximal inspiratory gas flow occurs when the: a. lung volume approaches total lung capacity. b. lung volume approaches residual volume. c. alveolar pressure is most negative. d. interpleural pressure is approximately...
Gas engines, also known as gasoline engines, are commonly found in cars. They work by igniting a fuel-air mixture with a spark plug. The intake stroke creates a vacuum, drawing in the mixture. During the compression stroke, the mixture is compressed, and when ignited, combustion occurs, gen...
