???????Can Anyone solve this

The diameter of a water pipe, shown below, changes gradually from \( 200 \mathrm{~mm} \) at point \( \mathrm{A} \) to \( 140 \mathrm{~mm} \) at point \( \mathrm{F} \) Point \( A \) is \( 4 \mathrm{~m} \) above the datum and point \( B \) is \( 5 \mathrm{~m} \) above the datum. The pressure at point \( A \) is \( 120 \mathrm{kN} / \mathrm{m}^{2} \) and the flow rate is \( 0.0662 \mathrm{~m}^{3} / \mathrm{s} \). Determine (i) the velocity at \( A \), (ii) the velocity at \( B \) and (iii) the pressure at point \( B \). \( \rho_{\text {water }} \) can be taken as \( 1000 \mathrm{~kg} / \mathrm{m}^{3} \)
