Why is a metal plate used in heat sinks?
because metal is a good conductor of energy (there are a lot of free electrons in a metal) and this will cause the metal to absorb and radiate more energy combined with the increased surface area of the heat sink
How does fire spread using conduction?
A fire in one part of a building can heat up some metal object that runs through a wall from the area of the fire to another location, as yet not affected by the fire. The fire in the first location makes the metal red hot and as metal is a good conductor, the heat travels along it, through the wall into the new area. If the metal in the new area is on contact with some combustible material this can then be set alight and the fire spreads.
What is in Cooling Fins on A Radiator?
Radiator have metal fins which increases total surface area of the metal body which cooling effect and hence increase the efficiency to maximum cooling effect.
Does a short thick metal wire or a long narrow metal wire have more resistance?
yes, Easy of flow of current increases with increase of area of cross section.
Aluminum bar 4inch dia weight per foot?
The weight is determined by the amount of metal contained in a one foot length of a 4 inch diameter round rod. To find the amount of the aluminum's weight by volume, do the following:Find the cross-sectional area of the circle at the end of the round rod:Radius (r) = diameter/2 = (4 inches)/2 = 2 inchesArea (A) = radius(squared) * PI = (2)^2 * 3.14159 = 12.566 square inchesMultiply by the length of the rod:Volume (V) = Area * Length = 12.566 sq.in. * 12 inches = 150.8 cubic inchesAccording to the page atWhat_is_the_weight_of_one_cubic_inch_of_6061_aluminum, the weight of one cubic inch of 6061 alluminum alloy is .0975 lb. So multiply the volume of the round rod in cubic inches by this weight:Total weight (W) = 150.8 cubic inches * .0975 lb. = 14.7 lb. (Answer!)If you happen to have had an Aluminum bar that was rectangular instead of round, the area would be instead calculated as A= width * height, and all subsequent calculations afterwards would remain the same.
What is the area of 8in 7in 10in?
560
What is the area of 6in and 10in?
A rectangle with sides of 6 inches and 10 inches would have an area of 60 square inches.
What is the area of a 10in circle?
Area of a circle = pi*radius squared
What is the area of a triangle with a base of 10in and an altitude of 14in?
70 square inches
How do you calculate injection pressure from product before injection molding?
By deviding the multification of line pressure and screw dia with the crosssectional area of hydralic cylinder piston.
Find the area of a circle when the circumference is 10in?
The area of a circle when the circumference is 10 inches is: 7.96 square inches.
What is the area of 14 in and 20 in and 10 in and 12 in?
Area = 14in x 20in = 280in2 Area = 10in x 12in = 120in2
A square and a triangle have equal areas and a side of the square is 10 inches and the base of the triangle is 10 inches then what is the height of the triangle?
Area triangle = 1/2 base x height Area square = length x width = 10in x 10in = 100sq in. Area triangle = area square Therefore: 1/2 x 10in x height = 100sq in height = 100 sq in x 2 / 10 in = 20 in
What is the square feet of 7ft 10in by 6ft 10in?
Multiply the two dimensions to get the area. In this case the calculation gives you 7,708 square inches, which divided by 144 gives you 53.53 square feet.
What is the cross sectional area of a 10 inch metal round duct?
Cross-sectional area = pi*radius2
What is the area of a rectangle with sides of 3 in by 10 in?
The area would be 30 square inches. To figure that out, you multiply 3in x 10in. You're Welcome. :)
Area of a parallelogram the base is 10 and the height is 24in?
This is the exact same answer as the area of a 10in x 24in rectangle. Essentially, you are multiplying the base and height of a rectangle to get its area, too.
