this topic might of been done before but how much water should a 4040 ro with water pressure of 50 produce in 24hrs mind you it is cold any help would be great thanks

this might give you an idea, mine produces 600L in roughly 5-6 hours with tap pressure of 80psi, so that should be 2400L in 24 hours, so with 50 psi, that is roughly 2/3 of my 80psi, so you may get 1600L, that is 2/3 of the 2400L that mine produces, maybe

Mine would produce about 2000 litres in 24 hrs if I had a tank big enough to hold it.
I've measured it (roughly) at 1 litre per 35 - 40 seconds.  40 seconds would be 90 litres an hour.
My water pressuyre is 40 - 50 PSI.
