The fire protection system below has a pump which draws water at $15$C from a reservoir and delivers it to Point B at $\backslash (105\backslash$mathrm$\{$~L$\}/\backslash$mathrm$\{$s$\}\backslash )$

A$)$ Calculate the height $($ h $)$ of the water level to maintain $35$ kPa at point A $.$

B$)$ Using this pressure at point $\backslash ($ A $\backslash ),$ calculate the power delivered to the water in order to maintain a pressure of $585$ kPa at point B $.$
