Parts manufactured for use on aircraft do face much tougher guidelines on design, construction, and quality control than those used in most industrial applications. A typical hydraulic pump used on an aircraft may cost between $4,000 and $25,000, compared with a comparable industrial pump's cost of $400 or less.
The temperature at the surface of the Sun is about 10,000 Fahrenheit (5,600 Celsius). The temperature rises from the surface of the Sun inward towards the very hot center of the Sun where it reaches about 27,000,000 Fahrenheit (15,000,000 Celsius).
Our Sun is a type G star, which are yellow stars with surface temperatures of about 6000 Â°C, or 11,000 Â°F. Type A stars, which are hotter, are white in color and maintain temperatures of around 10,000 Â°C or 18,000 Â°F. The hottest of the types, B and O, are blue stars while the coolest of type M are red in color and have surface temperatures of about 3,000 Â°C or 5,400 Â°F. Note that we have referred to the surface temperatures of stars thus far. Each star, however, ranges in interior ...
