Dear Scot. It's possible to estimate the pump size but you need a number of variables: water delivery (discharge) rate, pipe size (then calculate frictional head), static head etc.. Please refer to the FAO Irrigation Manual Module 5 found on the link below. ftp://ftp.fao.org/docrep/fao/010/ai594e/ai594e00.pdf Also check this link: http://www.pump-zone.com/december-2013-pump-sizing-efficient-irrigation
