Ch 11.1 Help

After playing around with number 3, this is what I did, and it worked

First of all, the answer on maple TA is positive, in the Cd it is negative (possibly an error)

Well, this is what I did:

I had 32.09 PSI so I multiplied it by (6.89*10^3)= 221100.1 (gauge pressure)

I then added this to atmospheric pressure (1.013*10^5)= 322400.1 (absolute pressure)

I then divided this sum by (1.013*10^5) to get the absolute pressure in atmospheres.

answer= 3.182627 (and it is POSITIVE)

It worked for me, I hope it helps you all. Good Luck!
