J. If the radius of a pipe narrows to half of its original size, what is the ratio of the flow speed in the narrow section to that in the wide section, assuming the same flow rate? Solution: V₁ = speed in narrow section V2 = speed in wide section A1 V₁ = A2 V2 V₁/V₂ = A₂/A1 = π (r/2)²/nr² V1/V2 = 14 SAQ 1. A 75 kg person's density changed from 970 kg/m³ to 990 kg/m³.
