Thread: Questions

Couple of questions here...all bunched together, did not want to start thread or have them each lost in threads.

Hope someone knows the answers....


How do you measure the volume of water in a tank in litres ? For both a round tank, not round as in like a football round, round as in made from concrete rings and a square tank.


How long do chicken eggs take to hatch.


Where do you get lint free rags....all my rags have lint so it seems.

volume is easy

just the area of the surface x the depth in centimetres

area of the surface is "pi" x diameter squared divided by 4

e.g internal diameter of your rings is 80 cm

so pi= 3.142

so 3,142 x 80 x 80 ¬ 4 (no division key)

same as 3.142 x 80 x 20 = 5027sq cm

multiply that by the depth of water, say 200cm

1005400 cu cm

divide by 1000 gives you litres

approx 1005 litres

a square tank is even easier

just mult the depth by width by breadth in cm and divide by 1000
