AI Generated Solution

To solve the problem, we need to determine the change in the area of cross-section of the pipe in order to achieve a pressure difference that is 1.5 times the initial pressure. Let's break this down step by step. ### Step-by-Step Solution: 1. **Identify the Initial Parameters:** - Let the initial area of cross-section of the pipe be \( A \). - Let the initial force of water from the pipe be \( F \). - The initial pressure \( P \) can be calculated using the formula: ...
