Answer:
The pressure inside the hose 7000 Pa to the nearest 1000 Pa.
<em></em>
<em></em>
The pressure at the site of the puncture is <em></em>
Explanation:
<em>According to Poiseuille's law, </em>
<em>Where is the pressure at a point before the leak, is the pressure at the point of the leak , μ = dynamic viscosity, L = the distance between points and , Q = flow rate, D = the diameter of the garden hose. </em>
<em>Also, from the equation , the equations and can be derived.</em>
Combining Poseuille's law with the above, we get
<em></em>
<em></em>
Since the hose has a uniform diameter, the nozzle at the end is closed and neither point <em> nor lie after the puncture,</em>
<em></em>
The pressure at the site of the puncture <em></em>
