(See q.) If current decreases at this point, the flow rate may not change by 135 mA due to hysteresis. (See w.) The flow rate at increasing current and decreasing current are not the same due to hysteresis. (q 85 l/min., e 93 l/min.) Condition 2. P1 = 0.7 MPa, P2 = 0.2 MPa Refer to curve B when P is 0.5 MPa.
