In Fig. P2.11, pressure gage $A$ reads $1.5 \mathrm{kPa}$ (gage). The fluids are at $20^{\circ} \mathrm{C}$. Determine the elevations $z$, in meters, of the liquid levels in the open piezometer tubes $B$ and $C$.
As shown in Fig. 1.6, a manometer is attached to a tank of gas in which the pressure is $104.0 \mathrm{kPa}$. The manometer liquid is mercury, with a density of $13.59 \mathrm{~g} / \mathrm{cm}^{3}$. If $g=9.81 \mathrm{~m} / \mathrm{s}^{2}$ and the atmospheric pressure is $101.33 \mathrm{kPa}$, calculate (a) the difference in mercury levels in the manometer, in $\mathrm{cm}$. (b) the gage pressure of the gas, in $\mathrm{kPa}$.
