In this problem, we would like to find the reading as indicated by the mercury column.
00:09
Okay, so to find the reading as indicated, we can write an expression for our affected bulb volume.
00:17
So we can write our, we can solve this expression.
00:25
We can say that our affected bulb volume is our volume that's given, so 79 .5 times our density plus 1 .13 times 10 times 10.
00:40
This is just thinking about our 10 centimeter height as well as our 10 centimeter height.
00:54
So now let's go ahead and plug this into a calculator.
00:58
We get 79 .5 times 1000 plus 1 .13 times 10 times 10.
01:06
We get 79613 millimeters cubed.
01:12
Now we have our pressure.
01:15
We can find our cross -sectional area, which is pi d squared over 4.
01:19
So pi 1 .1 squared over 4.
01:22
So let's plug that into a calculator.
01:24
Pi 1 .1 squared divided by 4 gives us 0 .950 millimeters squared...
