Solved My Solution's With Blue Pen And Chegg Solution With | Chegg.com To find the number of grains in a ballpoint pen ball, apply the astm grain size formula and calculate the total grains based on surface area and estimated volume of a single grain. the calculation results in one of the options provided in the question. Assume that the head of a pin is spherical with a 1 mm diameter and has an astm grain size of 12. the number of grains in a ball can be calculated using the formula: number of grains = (4/3) * pi * (radius)^3 * astm grain size. for the ball of a ballpoint pen: radius = diameter/2 = 1 mm / 2 = 0.5 mm. The volume of the ball can be calculated using the formula for the volume of a sphere: v = (4/3) * π * r^3, where r is the radius of the ball. since the diameter is given as 0.95 mm, the radius is half of that, which is 0.475 mm or 0.000475 m. Question: the ball of a ballpoint pen has a diameter of 1.7 mm, has an astm grain size of 10, and is made of steel (iron). how many grains are there in the ball? how many atoms of iron are there in a grain? assuming the balls have been highly cold worked, estimate the number of dislocations in a grain.

Your solution’s ready to go! our expert help has broken down your problem into an easy to learn solution you can count on. see answer. Given: the ball of a ballpoint pen is 1 mm in diameter, which means its radius (r) is 0.5 mm. the astm grain size is 10. to find: the total number of grains present in the ball. step 1: calculate the volume of the ball. the volume (v) of a sphere is calculated using the formula: v = π 3. Our expert help has broken down your problem into an easy to learn solution you can count on. Finally, we can divide the volume of the ball by the volume of one grain to get the number of grains in the ball: 0.0654 mm^3 / 2.27 x 10^ 6 mm^3 = 28,787 grains (rounded to the nearest whole number).
