Concept explainers

Fluid Pressure

The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.

Gauge Pressure

Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.

Question

The problem presented involves a house with a roof colored gray. The dimensions of the roof are illustrated in the drawing attached. The objective is to determine the magnitude of the net force that the atmosphere applies to the roof when the outside pressure experiences a sudden drop of 12.4 mm of mercury, prior to any pressure adjustment in the attic.

**Details from the Diagram:**

- The roof is sloped at an angle of 30.0°.
- The dimensions provided are:
- Length of the roof: 14.5 meters.
- Width of the roof: 4.21 meters.

**Calculation Requirement:**

- The effect of the atmospheric pressure drop (12.4 mm of mercury) on the roof needs to be assessed to determine the net force exerted.

**Input Section:**

- Number: [Input box for the calculated value]
- Units: [Dropdown menu for selecting appropriate units]

This scenario requires the application of physics principles related to pressure and force calculations.
