Hospital Laundry

The laundry department of a large hospital contains energy efficient industrial washing machines for laundering sheets and towels. High energy $($HE$)$ laundry detergent is automatically dispensed at the start of each load. If an insufficient amount of detergent is dispensed, the laundry will not be completely cleaned, while too much is unnecessarily costly and can damage the machine$$s bearings.
