In this question we want to determine the maximum length of the straw that we can use.
00:05
And for us to answer this question we are going to be using hydrostatic equations.
00:09
That is, from hydrostatic, the pressure of a fluid column is equal to the density multiplied by the acceleration due to gravity, multiplied by the height of that column.
00:20
And here we are interested in the height of this column, which is equal to the density multiplied by the specific rather the acceleration due to gravity.
00:28
So for us to answer this question, we are going to look at a situation where we have atmospheric pressure, one atmosphere, and if we are to convert this into pascal, this is 101325 pascal.
00:42
And the units of pascal are khees per meter second squared.
00:48
These are the si units.
00:50
So if we look at this and the density of h2o, density we are going to assume this to be 1 ,000 khease per, cubic meter and our acceleration to gravity this is going to be equal to 9 .81 meters per second square.
01:06
So if we use this information we're going to get our age being equal to 10 .33 meters.
01:15
All we did was to substitute these values into this formula to determine our age...
