💭 Think About

• What is the standard conversion factor between 1 inch of water column and psi? Write that down first. • If you multiply that conversion factor by 6 inches of water, what psi value do you get? • After calculating, which option is numerically closest to your result?

✅ Before You Answer

• Be sure you are using inches of water, not inches of mercury. • Confirm the conversion factor you use is in psi per inch of water, not the other way around. • After calculation, double‑check that your decimal place is reasonable for a low pressure like 6 inches of water.
