A pan mixer has a maximum batch size of 12m³ and operates with an 85% efficiency. If its cycle time is 4 minutes, calculate its hourly production rate. Assume the total operational time per hour is 60 minutes.
💡 Hint: Think about how efficiency and time interact to affect total output.
You are tasked with optimizing a trough mixer that currently operates at 60% efficiency. If you increase the efficiency to 75%, how much more concrete can you expect to produce in a standard 8-hour shift, assuming the batch size remains constant at 10m³ and cycle time is 5 minutes?
💡 Hint: Calculate the production rate adjustments based on efficiency.
