A clean room is designed for positive pressure 0.05" w.g. There is a 2 sqft opening on the wall. Calculate the leakage velocity and leakage rate at the opening.
If the positive pressure is changed to 0.1" w.g. What are the new leakage velocity and leakage rate?
What is the consequence if we change the design positive pressure from 0.05"w.g to 0.1"w.g?
