Consider a pipe line where water is flowing from section A to section B$.$ At Section A$,$ the pipe diameter is $0\mathrm{.}22m,$ pressure is $42$kPa, and elevation is $143m.$ At Section $B,$ the pipe has a diameter of $0\mathrm{.}4m,$ and elevation of $149m.$

Discharge of water is $0\mathrm{.}07\frac{m^3}{s},$ and head loss in the pipe is $2\mathrm{.}97m.$ Specific weight of water is $9810\frac{N}{m^3},$ and the value of $g=9\mathrm{.}81\frac{m}{s^2}.$ Find the pressure at B$.$ Solve the problem on A$4$ sheet of white paper, scan the solution and

upload the pdf file in vUWS against this question. Do not email the solution to the lecturer.
