Only need help with question c and e$.$A pipeline ABC connects two pressurised tanks with absolute pressure $P_A=1\mathrm{.}50{10}^{5}Pa$ for tank A and $P_C=1\mathrm{.}45{10}^{5}Pa$ for tank $C.$ The liquid surface of the tank $A$ is $3\mathrm{.}5m$ above the liquid surface of the tank $C.$ The pipe leaves the top tank $A$ at a depth of $1\mathrm{.}5m$ below its liquid surface. The pipe extends for $140m$ horizontally before it reaches point $B.$ At point $B$ there is a smooth and shallow angled bend and the pipe slopes down and enters into tank $C$ below its free surface. The length of pipe from point $B$ to the lower tank $C$ is $100m,$ and the pipe diameter is $0\mathrm{.}15m$ throughout the system.$($Answer flow rate$=0\mathrm{.}022)$

$($c$)$ Calculate the absolute and gauge pressures at point B $($assume a velocity if you need to$).$

$($e$)($i$)$ If this system is to be used to generate hydroelectric power, by positioning a turbine at the end of the pipe at the entrance to tank $C,$ calculate the power available from the system. Assume an average fluid velocity at point B of $0\mathrm{.}32m{s}^{-1}.$
