Problem $2\mathrm{.}12\mathrm{.}12$

The U$-$tube in Fig. P$2\mathrm{.}12\mathrm{.}12$ rotates at $2\mathrm{.}0re\frac{v}{s}.$ Find the absolute pressures at points C and B if

the atmospheric pressure is $14\mathrm{.}696$ psia $.$ Recall that $70F$ water evaporates at an absolute

pressure of $0\mathrm{.}363$ psia $.$ Determine the absolute pressures at points C and B if the U $-$tube rotates at

$2\mathrm{.}0re\frac{v}{s}.$

start with:

$p_B=p_{\text{a}\text{t}\text{m}}+gh$
