An ideal fluid,of density 0.85 × 10³ kg/m³,flows at 0.50 kg/s through a pipe of radius 0.010 m.What is the fluid speed? A) 0.95 m/s B) 1.9 m/s C) 3.0 m/s D) 0.94 m/s

Question

The fluid speed can be calculated using the formula for mass flow rate: mass flow rate = density × area × velocity. Rearranging for velocity gives velocity = mass flow rate / (density × area). The area of the pipe is πr² = π(0.010 m)². Substituting the given values, velocity = 0.50 kg/s / (0.85 × 10³ kg/m³ × π(0.010 m)²) ≈ 1.9 m/s.
