A centrifugal pump is used with gasoline (ρ = 680 kg/m³). Relevant dimensions are as follows: d₁ = 15 cm, d₂ = 28 cm, L = 9 cm, β₁ = 25°, and β₂ = 40°. The gasoline enters the pump parallel to the pump shaft when the pump operates at 1200 rpm. Determine (a) the flow rate, (b) the power delivered to the gasoline, and (c) the head in meters.
