In summary, the conversation is discussing the calculation of the net force pushing on a rectangular window in a house during a storm. The dimensions of the window are given, as well as the atmospheric pressure inside and outside the house. The equation P=F/A is mentioned, as well as the conversion between atmospheres and kilopascals. The attempt at a solution includes finding the area of the rectangle and using it to calculate the net force, but the units are incorrect.

Homework Statement



A rectangular window in a house has dimensions 3.20 m x 2.40 m. As a storm passes by, the air pressure outside drops to 0.948 atm while the pressure inside the house remains 1.00 atm. What is the magnitude of the net force pushing on the window?
Take atmospheric pressure to be 101 kPa

Homework Equations


P= F/A
Area of rectangle= 2(length + width)
1 atm = 101 kPa


The Attempt at a Solution



A = 2(3.2+2.4)= 11.2 m^3
P= 101 kPa (it only requires pressure inside house because that's the force of interest)

p=f/a
p*a=f
11.2* 101 kPa

what am i doing wrong? is it the units?:confused:

1. What is fluid pressure?

Fluid pressure is the force exerted by a fluid per unit area. It is typically measured in units of force per unit area, such as pounds per square inch (psi) or pascals (Pa).

2. How is fluid pressure calculated?

Fluid pressure can be calculated by dividing the force exerted by the fluid by the area over which the force is exerted. This can be written as P = F/A, where P is pressure, F is force, and A is area.

3. What factors affect fluid pressure?

The factors that can affect fluid pressure include the density of the fluid, the depth of the fluid, and the acceleration due to gravity. The shape and size of the container holding the fluid can also impact pressure.

4. What is the difference between fluid pressure and fluid force?

Fluid pressure refers to the force exerted by a fluid per unit area, while fluid force refers to the total force exerted by a fluid on an object. In other words, fluid pressure is a measure of the intensity of the force, while fluid force is a measure of the amount of force.

5. How does fluid pressure affect objects in a fluid?

Fluid pressure can affect objects in a fluid in several ways. For example, it can cause objects to float or sink, it can create buoyant forces, and it can cause objects to move if the pressure is unevenly distributed. In some cases, high fluid pressure can also damage or break objects.
