The pressure rise of a centrifugal pump (AP) can be expressed as a function of impeller diameter (D), angular velocity of the impeller (@), fluid density (p) and volumetric flow rate of the pump (Q). Upon conducting an experiment using water as the working fluids, the relationship between AP and Q can be obtained as in Table Q3, by setting o and D as 25n rad/s and 20 cm respectively. With the assistance of Buckingham Pi's theorem and data from Table Q3. predict the pressure rise at Q = 0.25 m?/s while o and D are remained. (Note: You need to express AP as a function of D, o, p and Q first).
