Question

Which of the following represents the highest pressure? A) 200 spa B) 25Psi C) 2 ATM D) 1500mmhg

Answer 1

A) 200 spa* = (probably 200kpa) = 200000 Pa
B) 25 Psi = 25 x 6.894757 kPa = 172.368925 kPa = 172368.925 Pa
C) 2 ATM = 2 x 101325 Pa = 202650 Pa
D) 1500 mmhg = 1500 x 133.322 Pa = 199983 Pa
*probably mistaken
Answer: C) 2 ATM.
