Water is siphoned from a tank whose surface is 6 m above the floor. The siphon outlet is 1.5 m above the floor and discharges to the atmosphere. Neglecting losses, what is the outlet velocity?

  1. 10.85 m/s
  2. 5.42 m/s
  3. 12.13 m/s
  4. 9.40 m/s

Answer

D. 9.40 m/s

Solution

V = sqrt(2gh) with h = 6 - 1.5 = 4.5 m: V = sqrt(2 × 9.81 × 4.5) = 9.40 m/s.
