A radial-flow pump has the following dimensions: B₁ = 44° B₂ = 30° r₁ = 21 mm r₂ = 66 mm b₁ b₂ = 11 mm 5 mm For a rotational speed of 2500 rev/min, assuming ideal conditions (frictionless flow, negligible vane thickness, perfect guidance), with a₁ = 90° (no prerotation), determine (a) the discharge, theoretical head, required power, and pressure rise across the impeller, and (b) the theoretical head-discharge curve. Use water as the fluid.

Question
A radial-flow pump has the following dimensions: B₁ r₁ = 21 mm 12 = 66 mm B₂ = 44° = 30° b₁ = 11 mm b₂ = 5 mm For a rotational speed of 2500 rev/min, assuming ideal conditions (frictionless flow, negligible vane thickness, perfect guidance), with α₁ = 90° (no prerotation), determine (a) the discharge, theoretical head, required power, and pressure rise across the impeller, and (b) the theoretical head-discharge curve. Use water as the fluid.
