Example (Bergonzo):
if a 140kg/h flow rate BERGONZO 45° nozzle is provided, set the return pressure at 13bar, supply at 20bar on
the delivery to get a 110kg/h flow rate. If the return pressure needed is 5bar, instead, act on the adjusting screw on the pressure gover-
nor. The flow rate will then be about 55kg/h (see the example showed on the Bergonzo diagram).
