1. The problem statement, all variables and given/known data A manometer using oil (density 0.91 g/cm3) as a fluid is connected to an air tank. Suddenly the pressure in the tank increases by 0.72 cm of Hg. (a) By how much does the fluid level rise in the side of the manometer that is open to the atmosphere? (b) What would your answer be if the manometer used mercury instead? 2. Relevant equations P = rho*gravity*height 3. The attempt at a solution I have looked at several options of solving this problem. None of them make any sense to me. Please help. Thankyou!!
