Problem 1.¶
Imagine two tanks (both open to air). Tank A is filled to a depth $h$ with water. Tank B is filled to a depth $h$ with oil.
Determine:
- Which tank has the largest pressure?
- Why?
- Where in the tank does the largest pressure occur?

Problem 3.¶
A device for measuring the specific weight of a liquid consists of a (U-,You-, or Ewe-) Tube manometer as depicted below. The manometer tube has an internal diameter of $0.5~cm$ and originally has water in it. Exactly $2~cm^3$ of unknown liquid is poured into one leg of the manometer, and a displacement of $5~cm$ is measured between the free surfaces as shown.
Determine:
- The specific weight of the unknown liquid?
