Question: Is there a quick way to estimate annual pumping costs for a given pipe size and flow rate?
Keywords: v1i14,pumping,pump,cost,annual,calculation,estimate,estimation
Answer: If set up in a spreadsheet, the formula below could easily be used with metric units of measure as well. For quick estimates, use a friction factor of 0.02 (probably a little conservative for most cases).
