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).
Answer by Plucas. Confidence votes 31.3K. The core of the sun is 15 million oK (Kelvin is the scientific scale) and the corona is 5800 oK. The corona is that temperature because sound waves produce intense heat and below the corona and photosphere are convection currents that bring heat to the surface. The surface of the Sun (the photosphere) is about 5500Â° Celsius (~5800Â°Kelvin).   The corona (outer atmosphere) has a much higher temperature, in the millions of â¦ degrees, but it is so comparatively tenuous that the effective heat energy is very much less.
