79 Questions for Chapter 11: Fluid Statics

  1. The outward force on one end of an air tank was calculated in Example 11.2. How is this force balanced? (The tank does not accelerate, so the force must be balanced.)?

  2. Why is force exerted by static fluids always perpendicular to a surface?

  3. In a remote location near the North Pole, an iceberg floats in a lake. Next to the lake (assume it is not frozen) sits a comparably sized glacier sitting on land. If both chunks of ice should melt due to rising global temperatures (and the melted ice all goes into the lake), which ice chunk would give the greatest increase in the level of the lake water, if any?

  6. What depth of mercury creates a pressure of 1.00atm?

  7. How do you convert pressure units like millimetres of mercury, centimetres of water, and inches of mercury into units like newtons per meter squared without resorting to a table of pressure conversion factors?

  8. The greatest ocean depths on the Earth are found in the Marianas Trench near the Philippines. Calculate the pressure due to the ocean at the bottom of this trench, given its depth is11.0kmand assuming the density of seawater is constant all the way down.

  9. Atmospheric pressure exerts a large force (equal to the weight of the atmosphere above your body—abouttons) on the top of your body when you are lying on the beach sunbathing. Why are you able to get up?

    Found on Page 395
  10. Why does atmospheric pressure decrease more rapidly than linearly with altitude?
