Need help with this wuation.   Can it be solved with only the given information? What is the duct velocity if air flows in a duct under a Velocity Pressure of 2.24 inches of water?

Solution

Solution:

Yes it can be calculated since there is relation between Veclotiy pressure and Velocity.

The relation is as follows

Velocity pressure = (Velocity/4005)²

Hence 2.24= V²/16040025

Hence V= 5994.14 Ft/min
