In lieu of buying an actual air pump to use just once a year to close a swimming pool before freezing, I'd like to use the blower feature of a wet/dry vac.
I'm trying to choose between a 5HP and a 6HP (both peak) wet/dry vacs. Will the extra 1HP make any difference in the strength of pushing a 10-12ft column of water?
How do I determine the HP needed for a given column of water?

I don't think this is going to work.
Shop-vac posts their specs here: https://www.shopvac.com/specifications/quiet_series.asp
Even their most powerful vacuum only has a sealed pressure of 64 inches. I would presume that the blower would have the same pressure.
I don't know specifically what you are using an air pump for to close a pool but I think you may need to use a compressor or some other device.
Good luck!
