One of the dangers of tornadoes and hurricanes is the rapid drop in air pressure that is associated with such storms. Assume that the air pressure inside sealed house is 1.02atm whne a hurricane hits. The hurricane rapidly decreases th external air pressure to 0.910atm. What net force is exerted on a square window of 2.02m per side?

Respuesta :

Answer:

The net force is exerted on a square window of 2.02m per side = 45.5 kN

Explanation:

Pressure (P) is related to Force (F) and the perpendicular surface area of application of the force (A) through the expression,

P = (F/A)

F = PA

The net force is given as

F = ΔP × A

ΔP = (1.02 - 0.910) = 0.11 atm = 0.11 × 101325

= 11,145.75 Pa

A = 2.02 × 2.02 = 4.0804 m²

F = ΔP × A

F = 11,145.75 × 4.0804 = 45,479.1183 N

= 45.5 kN

Hope this Helps!!!
