Question 17 = A radial-flow pump has dimensions of ß₁ = 44°, ß₂ = 25°, r₁ = 21 mm, r₂ = 76 mm, b₁ 15 mm and b₂ = 7 mm. For a rotational speed of 2200 rev/min, assume ideal condition with no prerotation (α = 90°). If the head discharge curve is expressed as a function of volume flow rate, Q-i.e. H₁ = ao — a₁Q, determine ao and α₁.
