A boat is tied to a dock by a line from the stern of the boat to the dock. A pump inside the boat takes water in through the bow and discharges it out the stern at a rate of $3 \mathrm{ft}^{3} / \mathrm{s}$ through a pipe running through the hull. The pipe inside area is $0.25 \mathrm{ft}^{2}$ at the bow and $0.15 \mathrm{ft}^{2}$ at the stern. Calculate the tension on the line, assuming inlet and outlet pressures are equal.
