WebMar 30, 2012 · A reduction in orifice size results in decreased flow as only so much liquid can pass through the orifice. In all of the above cases, the inlet pressure is constant and the outlet pressure is, effectively, zero (atmospheric) as there is nothing to restrict flow on the exit side of the orifice. How much liquid passes through the orifice depends ...
