4.3. Factors Affecting Volume Measurement

Try these first

1. 1.

   What happens to air density at higher altitudes?

   Hint

   Think about how breathing feels at high altitudes.

2. 2.

   What does a turbocharger do?

   Hint

   Remember how turbocharged engines perform better under pressure.

3. 3.

   What is the primary effect of altitude on internal combustion engines?

   • Increases horsepower
   • Decreases air density
   • Improves fuel efficiency

   Hint

   Consider how it feels to breathe at high altitudes.

4. 4.

   True or False: Turbochargers are used to decrease air intake at high altitudes.

   • True
   • False

   Hint

   Think about how supercharging enhances performance.

5. 5.

   Given a bulldozer with a base horsepower of 200 at sea level, determine the probable horsepower at 10,000 feet elevation. Use a reduction of 3% per 1,000 feet to calculate.

   Hint

   Apply the percentage reduction effectively, multiplying its effect on the base horsepower.

6. 6.

   If a construction team shifts operations from sea level to a mountain site, which performance metrics should they consider adjusting in their plans?

   Hint

   Consider all factors affecting machinery performance in new environments.
