Conveyor Capacity Calculations need help please!

[jmsdg01]

Hi need help with this problem. I have been on the project management for quite some time and so I have already forgotten how to compute for this. Please share your thoughts on this problem.

Given:

1. unloader discharges via gravity, with a capacity of 300 tons/hour suction.
2. conveyor capacity = 250tons/hr
3. current conveyor capacity = 237 tons/hr
4. product weight is constant.

Main question, will the capacity increase if discharge spout from unloader is increased to a specific dimension?
