P1 = 0.7 MPa, P2 = 0.2 MPa Refer to curve B when P is 0.5 MPa. Ex) At increasing current, the flow rate when 150 mA current is applied is 65 l/min. (See r.) If the outlet pressure P2 increases by 0.15 MPa, P decreases by 0.15 MPa and becomes 0.35 MPa (See curve C), and the flow rate when the same current is applied is 40 l/min. (See t.)
