Question

When the wind blows, it creates pressure on any surface it blows against. A large window has an area of 6.5 sq. m. If the wind causes a pressure of 50 000 Pa on the window, what force acts on it?

Answer 1

Provided that:

• Pressure = 50,000 Pascal
• Area = 6.5 metre sq.

To calculate:

• The force

Solution:

• The force = 3,25,000 N

Using concept:

• Pressure formula

Using formula:

• P = F/A

Where, P denotes pressure, F denotes force and A denotes area.

Required solution:

→ Pressure = Force/Area

→ P = F/A

→ 50,000 = F/6.5

→ 50,000 × 6.5 = F

→ F = 3,25,000 N

→ Force = 3,25,000 Newton

Answer 2

• Pressure=50000Pa
• Area=6.5m^2

We know

$\boxed{\sf Pressure=\dfrac{Force}{Area}}$

$\\ \sf\longmapsto Force=Pressure\times Area$

$\\ \sf\longmapsto Force=50000\times 6.5$

$\\ \sf\longmapsto Force=3,25,000N$

$\\ \sf\longmapsto Force=325kN$
