$1.$The U$-$tube manometer is connected to water flowing in pipes at A and B$.$ The bottom segment of the manometer is filled with glycerine $($SG$=1\mathrm{.}26),$ and the pressure at $A$ is $10$kPa. The fluid levels in each segment are: $W=180mm$;$x=245mm$;$Y=231mm$;$Z=78mm.$ Determine the pressure at $B$ in kPa and round to two decimals $($e$.$g$.12\mathrm{.}45$kPa $).{}_w=9\mathrm{.}81k\frac{N}{m^3}.$

A $0\mathrm{.}4m$ thick layer of crude oil $(SG=0\mathrm{.}81)$ lies on top of a $1\mathrm{.}5m$ thick layer of seawater $)=(1\mathrm{.}03.$ The surface of the crude oil is in contact with the atmosphere. What is the mana nreccire at the hnttom of the water? Provide your answer in units of kPa and round to $2$ decimal places $($e$.$g$.,14\mathrm{.}83$kPa $).$ Need both
