2. Water $\left(?=1000\mathrm{kg}/{\mathrm{m}}^3\right)$ flows from the large orifice at the bottom of the tank as shown. Assume that the flow is irrotational. Point $\mathrm{B}$ is at zero elevation, and point $\mathrm{A}$ is at $0.3\mathrm{m}$ elevation. If ${\mathrm{V}}_{\mathrm{A}}=1.2\mathrm{m}/\mathrm{s}$ at an angle of $45^{?}$ with the horizontal and if ${\mathrm{V}}_{\mathrm{B}}=$ $3.6\mathrm{m}/\mathrm{s}$ vertically downward, what is the value of ${\mathrm{P}}_{\mathrm{A}}?{\mathrm{P}}_{\mathrm{B}}$ ?
