Question:

Suppose the wind speed in a hurricane is 96 mph (mi/h).

(a) Find the difference in air pressure (Pa) outside a home and inside a home (where the wind speed is zero). The density of air is 1.29 kg/m{eq}^3 {/eq}.

(b) If a window is 61 cm wide and 108 cm high, find the net force (lb) on the window due to the pressure difference inside and outside the home.

Force:

When the body experiences a pull or push and gets displaced from its initial position, then it is said to be a force. It is a measurable quantity that would be measured in Newton, and it shows only direction, not the magnitude, that's why it is said to be a vector quantity.

Given Data:

  • The speed of wind outside the home is, {eq}{v_1} = 96\;{\rm{mph}}= 42.88\;{\rm{m/s}} {/eq}
  • The speed of wind inside the home is,...
