Equations 10 , 11 represent the regression equations for head and HI respectively: Y 1 = 1.84 − 0.0514 A + 0.0624 B − 0.0184 C − 0.1432 D + 0.1209 E + 0.0518 F − 0.0441 G (10) Y 2 = 1.13 − 0.0376 A + 0.0511 B − 0.01118 C + 0.0459 D + 0.0316 E + 0.0131 F + 0.0371 G (11) From the constructed regression equations, it can be observed that the P-values for factors D and E are both less than 0.01, indicating that diffuser inlet angle D and diffuser wrap angle E have highly significant effects on head, with the significance order being D > E .
