Question $3$

If the gate value at $A$ is fully opened and at A $.$ determine the pressure just to the the pump produces a pressure of $350$ kPa remains closed. The pipe and gate vatight of the tee connection $C.$ The valve at $Bf=0\mathrm{.}04.$ Include the minor losses of value both have an inner diameter of $30$ mm $,$ and resistance coefficient of the tee is $0\mathrm{.}4$ the, elbows and the gate valve. The is $0\mathrm{.}19.$

Question $4$

$[12$ Marks$]$

Two pipes of identical diameters and material are connected in parallel. The length of pipe $A$ is twice the length of pipe $B.$ Assuming the flow is fully turbulent in both pipes and thus the friction factor is independent of the Reynolds number and neglecting all minor losses. With an aid of a diagram, determine the ratio of the flow rates in the two pipes.
