Cost function for sludge pumping:
The original cost function (A1) for pumping sludge is as follows:
This has as variable (x) the sludge pumping rate in gallons per minute. Applying the conversion factors from gallons per minute to liters per second, applying a factor of 5% which represents the sludge production that occurs in a plant and applying the elasticity factor, the function obtained is as follows.
