Rewrite this relationship in dimensionless form.
00:04
So for period, our dimensions are of period.
00:10
For density, we have ml to the negative 3 power.
00:15
For lambda, we have l.
00:18
For depth, we have l.
00:22
For gravity, we have l -t to the negative 2 power.
00:26
And for surface tension y, we have m -t to the negative 2 power.
00:33
We know that these repeating variables can form a pi group and we need to add other variables to form these groups.
00:42
So we can substitute our dimensions into our above expression.
00:47
For our first pi term, we have pi 1 is equal to row a, lambda, b, g, c, t.
00:54
So we have m -0, l -0, t -0 is equal to ml.
01:02
All we're doing is substituting our dimensions.
01:06
Then we have lt to the negative 2c times t...
