Challenge Problems

Push your limits with challenges.

Question 1

A gasoline engine has a theoretical consumption rate of 0.06 gallons/hour. A project requires adjustment due to poor load and time factors resulting in a load factor of 0.4 and a time factor of 0.5. Calculate the new consumption rate.

💡 Hint: Multiply the base consumption by load and time factors.

Question 2

An excavator operates at 300 horsepower with a fuel consumption factor of 0.25 gallons/hp hour. If its operating efficiency is 70% for 40 minutes per hour, calculate the hourly fuel consumption and cost if fuel is 70 rupees per liter.

💡 Hint: Calculate using the horsepower, consumption rate, and then apply the cost.
