3. Fluid Mechanics

Try these first

1. 1.

   Define density.

   Hint

   Think of the formula mass/volume.

2. 2.

   What does specific gravity measure?

   Hint

   Consider how it relates to water's density.

3. 3.

   What is density?

   Hint

   Consider the relationship between mass and volume.

4. 4.

   True or False: Specific gravity is the weight of a substance in water.

   • True
   • False

   Hint

   Think about what specific gravity compares.

5. 5.

   A cylindrical tank has a height of 2 meters and a radius of 1 meter, fully filled with water. Calculate the mass of water in the tank.

   Hint

   Use the formula for the volume of a cylinder.

6. 6.

   A fluid has a specific gravity of 0.8. What is its density in kg/m³?

   Hint

   Recall that specific gravity compares to water's density.
