Hydraulics?

[charles]

Who on here knows their stuff on hydraulics? Doing a build and want to power as much via hydraulics as possible. Have a 100 hp @ 2200 rpm, cummins 3.9 bt for power plant. 4, maybe 5 motors needed, 1 needs to be high tq, low spd (nmt 800 rpm) or high speed, turned down for plenty of tq. Tq values will NOT be constent and everything iv been reading for the past 2 wks, says of the 3 required values in hydro operations, design off tq value first and work backwards to pump. With tq unknow and mostly ever changing, how/where would 1 start to get a close estimate on tq values?
