Question

Explain why holes are made in banners and hoardings.

Show answer Hide answer
Answer
The holes let wind pass through, reducing the pressure difference so the banner is not blown down.

Explanation

  • High-speed wind blowing across a banner lowers the air pressure on that side.
  • This creates a large pressure difference that could tear or topple the banner.
  • Holes let the wind pass straight through, reducing this pressure difference.
  • So banners and hoardings with holes are less likely to be blown down.
Holes let wind through, lowering the pressure difference so the banner stays up.
