Your suggested mixer size is way too large for your tote.  To mix 340 gallons of a 100 cp fluid with a 1 sp gr requires only about a 1/2 hp mixer at 350 rpm.  A 350 rpm mixer with a 1/2 hp motor would normally be supplied with a 5-inch hydrofoil impeller.  However, if a 45-deg pitched turbine were used (but not recommended), it would only be about 3.5 inches in diameter.
 
A 14-inch diameter pitched turbine would overload a 2-hp motor at 350 rpm.  A 2-hp mixer with any impeller would be more mixing than you need in 340 gallons.
