Professional Analysis on Air Pressure Inside a House
What is the relationship between air pressure and the total force exerted by the air inside a house?
Consider a house at sea level that has 2500 square feet of floor area. What is the total force that the air inside the house exerts upward on the ceiling?
Answer:
Total Force that the air inside the house exerts upward on the ceiling is 5.25 × 10⁶ lb
When analyzing the air pressure inside a house at sea level with 2500 square feet of floor area, we must understand that the total force exerted by the air is directly proportional to the atmospheric pressure and the floor area.
The formula to calculate the total force is: Total Force = Atmospheric Pressure × Floor Area
Given that the Standard Atmospheric Pressure is 2100 lb/ft² and the Floor Area is 2500 ft², we can substitute the values into the formula to find the total force.
Therefore, Total Force = 2100 lb/ft² × 2500 ft² = 5.25 × 10⁶ lb. This means that the air inside the house exerts a total force of 5.25 × 10⁶ pounds upward on the ceiling.
This analysis showcases the relationship between air pressure, floor area, and the total force exerted by the air inside a house. Understanding these concepts is essential in engineering and architectural design to ensure structural integrity and safety.
