A friend of mine is a carpet cleaner with a hose and pumping rig in his truck. He often gets requests to clean carpets in condo's several stories above ground. The question is: How high off the ground can he expect to be able to service his customers?
If we assume that:
1. the pump is mounted on the truck
2. the power source is limited to a 3/4 HP motor at 120 volts
3. electrical power is most convenient from a duplex receptacle within 50' of the truck
4. the water comes from a hose bib supplying city water at approximately 40 psi, within 50' of the truck, and fed to the truck with a 3/4 to 1" rubber hose
5. the output side of the pump is also a 1/2 to 3/4" rubber hose
6. Ground level is within a few feet of sea level
7. assuming a story of a building is 12-15'
What would be the maximum size pump he could use, and how many stories off the ground could he pump the water with out increasing the the hose or motor size?
