Q 
Elkhart eductors Deerfield Beach trucks.
Eductor psi rated capacity.
Nozzle gpm/psi
Max hose lay
Effective reach
Friction loss 1.5 and 2.5
A 
200psi
95gpm/100psi nozzle
Nozzle must match flow of the eductor
If pumping less than rated 200psi you will have higher percentage of foam. Visa versa.
Nozzle must be fully open
12-15 second delay once inserting into concentrate
Add 5psi per 10ft elevation
Max hose lay 250ft
Effective reach 99ft
1.5 equals 22psi friction loss
2.5 equals 2psi friction loss
