Consider the flow in a U-bend in a pipe. Water is flowing at a rate of \(80 \mathrm{~cm}^{3} / \mathrm{s}\) in a pipe of diameter \(10 \mathrm{~cm}\). The inlet pressure is \(1.2 \mathrm{~atm}\). The friction loss is estimated as if the bend were equivalent to a straight pipe of length 75 times the diameter. The density is \(ho=1000 \mathrm{~kg} / \mathrm{m}^{3}\) and the viscosity is \(\mu=0.001 \mathrm{~Pa} \cdot \mathrm{s}\).

Find the exit pressure.

Find the force exerted by the flowing fluid on the pipe.
