Challenge Problems
Push your limits with challenges.
Question 1
A construction site requires 200 cubic meters of concrete that needs to be mixed in increments of 25 cubic meters at a time using a pan mixer that has a nominal capacity of 2000 liters. Calculate how many batches must be mixed to achieve the required amount and the minimum mixing time is 10 minutes per batch.
💡 Hint: Convert cubic meters to liters before working through the calculation.
Question 2
In a comparison study, a pan mixer produces concrete with a 15% higher efficiency compared to a traditional free fall mixer. If the free fall mixer produces 45 cubic meters per hour, calculate the output of the pan mixer.
💡 Hint: Reflect on how efficiency percentages alter total output.
