$2-$from problem on $2-7.$

Show computations, procedures and solution values for the following:

The differential manometer is filled with water $(20C)$ in sections A$-$C and B$-$D and the fluid in section C$-$D has density ${}_{CD}=1111k\frac{g}{m^3},$ and Patm $=101$kPa.

Do the following:

$($A$)$ Compute pressure at point $B,P_B(kPa),$ if pressure at point $A,P_A=50$kPa

$($B$)$ Pressure at point $C,P_C(kPa),$ if pressure at point $B,P_B=50$kPa

$($C$)$ Compute absolute pressure at point $C,P_C(kPa),$ if pressure at point $A,P_A=100$kPa

$($D$)$ Compute pressure head $(m)$ at $C,$ hc$,$ if pressure at point $D,P_D=50$kPa
