SUMMARY

The discussion centers on calculating the force exerted on a surface by gas pressure within a cube-shaped container. The pressure is given as 3.7 x 105 Pa, and the container has a side length of 0.10 m. To find the force on the south side of the container, one must first determine the surface area of that face, which is 0.01 m2. The force can then be calculated using the formula: Force = Pressure x Area, resulting in a force of 3.7 kN.

PREREQUISITES
  • Understanding of pressure units, specifically Pascals (Pa)
  • Basic knowledge of force and area calculations
  • Familiarity with the formula for calculating force from pressure
  • Concept of surface area for geometric shapes, particularly cubes
NEXT STEPS
  • Learn about the relationship between pressure, force, and area in fluid mechanics
  • Study the concept of Pascal's Law and its applications
  • Explore calculations involving different shapes and their surface areas
  • Investigate real-world applications of pressure calculations in engineering
USEFUL FOR

Students in physics, engineers working with fluid dynamics, and anyone interested in understanding pressure-related calculations in practical scenarios.

I've been having trouble figuring out this question:

A container is filled with gas at a pressure of 3.7 times 10^5 Pa. The container is a cube, 0.10 m on a side, with one side facing south. What is the magnitude of the force on the south side of the container due to the gas inside? Answer must be in kN.

Thanks to those that help :)

Welcome to the PF.

What are the sub-units of Pascals? If a Pa is a unit of pressure, it will be made up of units of Force and Area, correct? What are Pa in terms of Newtons and square meters? What is the surface area of that face they are asking about? So then, what would be the total force on that face from the pressure?
