MorePROFESSOR RACHEL MILLS: So we know our bucket here is 10 litres and the water is flowing in at about a litre a minute. So we can calculate the average time a water molecule will spend in the bucket. It’s the volume of the bucket 10 divided by about a litre a minute. So the water spends 10 minutes in the bucket before it overflows over the side.
