2.b) In reference to problem (2.a) above, while maintaining a constant steady water flow rate of 0.25 m/min, discuss without calculations: i. ii. iii. The effect of changing angle 0 between 0 and 90 on the magnitude of FH and Fv, while keeping Di and D2 same as above. The effect of making D = D2 = 5 cm, while keeping 0 = 65, on the magnitude of FH and Fv. If D1, D2 and 0 are kept at 5 cm, 3 cm, and 65, respectively, what is the effect of box volume on the magnitude of FH and Fv? (6 Marks)
