Push your limits with advanced challenges
A construction project requires heavy machinery operated 10 hours daily. The diesel engine rated at 600 hp has a fuel consumption factor of 0.05 gallons per horsepower hour. Calculate the total fuel consumed over a week, given the cost of diesel is 80 rupees per gallon.
💡 Hint: Calculate daily consumption first, then multiply by 7 for the total week.
If a machine has an operating factor of 0.6, a fuel consumption factor of 0.3 liters per horsepower hour, and runs at 500 horsepower, calculate the hourly cost of fuel when local price is 75 rupees per liter.
💡 Hint: Multiplication will lead you to fuel consumed first, use price afterward.
