Question

Water (ρ = 1,000 kg/m³) moves through a constricted pipe from the left. The flow is considered ideal. At the lower point, the pressure is P₁ = 5 × 10⁴ Pa and the pipe diameter is 4.0 cm. At another point y = 2.8 m higher, the pressure is P₂ = 1×10⁴ Pa and the pipe diameter is 2.0 cm. Determine the velocity (in m/s) of water at the lower point. Give your answer to 1 decimal place.

Useful Information

Use g = 10 m/s²
density of water is 1,000kg/m³
air pressure at sea level = 10⁵ Pascal
