What is coefficient of superficial expansion?
The coefficient of superficial expansion refers to the ratio of change in area to an increase in its temperature. It measures the expansion of a Laminar surface.
A material has a coefficient of volume expansion of 60×10^-6/degree celsius. What is its coefficient of expansion?
120×10^-6
Why liquids have two coefficient of expansion?
Because liquids have two types of expansions i.e Apparent Expansion and Real Expansion
Why is it necessary to know the coefficient of linear expansion of solids?
By knowing the coefficient of linear expansion of solids, you can determine how a solid reacts to temperature. Everything reacts to thermal expansion. For instance, a concrete bridge expands when hot, and with the formula for expansion and the coefficient for it, you know just how much that concrete expands and you can plan and build accordingly. That saves lives.
Water expands as it freezes can you define a coefficient of volume expansion for the freezing force?
The coefficient of the thermal expansion of water is equal to .00021. Water expands by 9% of its volume when it freezes.
Why aluminum has high thermal expansion coefficient than Copper?
Why aluminium has high thermal expansion coefficient than Copper?"
A copper water pipe is 10.000 meters long when installed in a building on a day when the temperature is 9.0 degrees C. How much does the pipe expand when it carries hot water at 87 degrees C?
The coefficient of expansion CTE) for copper is 16.6 x 10 to the negative 6 power per degree C. The expansion is CTE x TEMP CHANGE x LENGTH = 16.6 x 10 x 78 / 1000000 = 0.013 meters
Who invented the 's' bend pipe and why?
Eli Whitney after he developed the steam engine to allow for the coefficient of expansion per degree of temperature changes also called an expansion loop
What is the cubical coefficient of thermal expansion for metals?
Since most metals are isotropic, the cubical coefficient of expansion is three times the linear coefficient of expansion. The linear coefficient of expansion is obtained from measurement and tables for the specific material which are readily available.
How much does copper pipe shrink?
That would depend on the temperature /pressure as the coeffient of expansion per degree
What is coefficient of superficial expansion?
The coefficient of superficial expansion refers to the ratio of change in area to an increase in its temperature. It measures the expansion of a Laminar surface.
What is the Coefficient of thermal expansion for brass?
assuming it is pure copper and not an alloy, 17(k), 9.3 Co
What is the coefficient of expansion of brass?
.000019
What is a binomial coefficient?
A binomial coefficient is a coefficient of any of the terms in the expansion of the binomial (x+y)^n.
What is the coefficient of the x2y term in the expansion of (x 2y)3?
The coefficient is 6.
Does the coefficient of linear expansion depends upon length?
yes,according to relation coefficient of linear expansion depends upon original length.
Can a amateur run a new line of copper pipe for main source water lines?
Yes as it takes about 5 minutes to teach an 8 year old how to clean and properly solder copper fittings... The only problem is learning how to size the piping system to prevent erosion and learn to compensate for the coefficient of expansion per degree of temperature change to prevent a noisy system
