The diameter of a hole drilled through aluminum at 22°C is 7.50 mm. Find the diameter and the area of the hole at 89°C.Aluminum okorder.com/ So 7.50 * 22.2 * 10-6 * 89 = 0.0111555 mm diameter increase (should only report 3 sig figs, so 7.51 mm). The area is then pi / 4 * d^2 = 44.31017 (so 44.3) mm^2If i was once you, i might depart a small 1cm gap on the high and cover it with mesh - these round ones don\'t appear to allow a lot air flow in any respect in my viv and i have three... I have a tendency to simply leave the glass open a bit of at both aspect. You\'ll have got to use a great mesh although to stop bugs escaping via it. BTW - i think you will have to make it slightly deeper... 1.5 at least in case you are maintaining reps a good way to grow to 12inch plus.Other related question
