2.3.1. Problem 6: Pressure Increase in Water Pipe

Try these first

1. 1.

   What is Pascal's Law?

   Hint

   Think about how forces in fluids transfer.

2. 2.

   Define manometer.

   Hint

   Consider its role in fluid pressure measurement.

3. 3.

   What principle states that pressure applied to a confined fluid is transmitted equally throughout?

   • Bernoulli's Principle
   • Pascal's Law
   • Continuity Principle

   Hint

   Consider the implications of pressure in a fluid system.

4. 4.

   True or False? Higher density fluids always sit below lower density fluids in a column.

   • True
   • False

   Hint

   Think about how buoyancy works in fluids.

5. 5.

   If a manometer connected to a water pipe shows a discrepancy of 25 cm between water and oil with density 800 kg/m³. How much pressure must be adjusted in the water pipe to balance the manometer?

   Hint

   Keep in mind the specific gravities and how they relate to pressure.

6. 6.

   A container filled with oil and water is subjected to a pressure increase of 12 kPa. Determine how this change affects the height of fluid levels in a connected manometer with mercury.

   Hint

   What is the relationship between density, pressure, and height in this system?
