Answer: The head loss is 1.5 cm
Explanation: Equation needed to solve is:
where C is the friction coefficient. To determine the area of flow, we nee to realize that the area available for flow over an area of 1*1 m, Aₓ= 0.87 m², observed from the correlation that for every width of 5.0 cm, we lose 6.5 mm, roughly about 12.9 or 13%.
For a fresh clean screen, the velocity will tend to increase by a factor of (1/0.87).
The velocities through the screen equals to (0.4/0.87) = 0.46 m/s and (0.8/0.87) = 0.92 m/s.
Apply the above mentioned equation:
