Show me the steps to solve $.$ A spray system is shown in the diagram. Water is supplied at pressure P$=10$ Kpa, through the flanged opening of area A$=0\mathrm{.}002$ m$2.$ The water leaves in a steady free jet at atmospheric pressure. The jet area and speed area A$=0\mathrm{.}0006$ m$2$ and V$=4\mathrm{.}5$ m$/$s$.$ The mass of the spray system is $0\mathrm{.}1$ kg and it contains V$=0\mathrm{.}0002$ m$3$ of water. Find the force exerted on the supply pipe by the spray system.
