Challenge Problems

Push your limits with challenges.

Question 1

A construction project is planned at 10,000 feet elevation. The engine has a rating of 250 HP at sea level. Calculate the horsepower loss at this altitude (using an average of 20% loss per 5,000 feet).

💡 Hint: Consider the percentage loss formula based on elevation change.

Question 2

You are evaluating two machines for a project at a high altitude. Machine A with a turbocharger has a rated horsepower loss of 10% at 5,000 feet. Machine B without a turbocharger loses 20% at the same altitude. If both have 300 HP at sea level, determine the effective horsepower for each at 5,000 feet.

💡 Hint: Calculate the adjusted horsepower by determining the percentage deduction for each machine.
