Final answer:
The pressure in a water pipe can be calculated using the equation P = F/A. In order to calculate the pressure in specific scenarios, we need to use the given information and apply the appropriate formulas.
Step-by-step explanation:
The pressure in a water pipe can be calculated using the equation P = F/A, where P is the pressure, F is the force exerted on the area, and A is the cross-sectional area of the pipe.
In order to calculate the pressure in the specific scenarios mentioned, we need to use the given information and apply the appropriate formulas.
For the first scenario where the pressure drops and the flow rate decreases, we can use the equation P1/A1 = P2/A2 to find the new pressure.
