This document addresses three fundamental problems in fluid mechanics related to pressure and force. It begins by calculating the pressure exerted by a force of 200N over an area of 4m². Next, it determines the force exerted by a gas at 150,000 Pa on an object with a surface area of 3m² by rearranging the pressure formula. Finally, it computes the area that will experience a force of 6000N from a liquid exerting a pressure of 300kPa, again utilizing formula rearrangement. These exercises assist in grasping core principles of pressure and force relationships.
