Question

velocity of water in a horizontal pipe is 4.9m/s.find the velocity head of water

Answer 1

velocity head = 1/2 ρ  v² 
                      = 1/2 * 1000 kg/m³ * 4.9²  m²/s²
                      = 12, 005 N/m²  or  J/m³  or Pa

Answer 2

Answer:

1.225m

Explanation:

velocity head = v²/2g = 4.9²/2×9.8=1.225m
