The vacuum pressure of a condenser is given to be 80 kPa. If the atmospheric pressure is 98 kPa, what is the gage pressure and absolute pressure in kPa, $kN/m^2, lbf/in^2,$ psi, and mmHg.

The vacuum pressure of a condenser is given to be $65\ \mathrm{kPa}$. If the atmospheric pressure is $98\ \mathrm{kPa}$, find the gage pressure and absolute pressure in $\mathrm{kPa}, \mathrm{kN} / \mathrm{m}^2, \mathrm{lbf} / \mathrm{in}^2$, psi, and $\mathrm{mmHg}$.

Determine the atmospheric pressure at a location where the barometric reading is 735 mmHg. Take the density of mercury to be $13,600 kg/m^3.$

If the pressure inside a rubber balloon is 1500 mmHg, what is this pressure in pounds-force per square inch (psi)?

Consider a tank of rectangular cross-section partially filled with a liquid placed on an inclined surface, as shown in the figure. When frictional effects are negligible, show that the slope of the liquid surface will be the same as the slope of the inclined surface when the tank is released. What can you say about the slope of the free surface when the friction is significant?

A diver's watch resists an absolute pressure of $5.5$ bar. At an ocean having a density of $1025 \mathrm{~kg} / \mathrm{m}^3$ and exposing an atmospheric pressure of $1 \mathrm{bar}$, what depth can maximally the diver dive to prevent water inlet into his watch? $1 \mathrm{bar}=10^5 \mathrm{~Pa}$ and $g=9.81 \mathrm{~m} / \mathrm{s}^2$.

A pressure gage connected to a tank reads 500 kPa at a location where the atmospheric pressure is 94 kPa. Determine the absolute pressure in the tank.

The gage pressure in a liquid at a depth of 3 m is read to be 42 kPa. Determine the gage pressure in the same liquid at a depth of 9 m.

Determine the atmospheric pressure at a location where the barometric reading is 750 mmHg. Take the density of mercury to be $13,600 \mathrm{kg} / \mathrm{m}^{3}$.

A pressure gage connected to a tank reads 50 psi at a location where the barometric reading is 29.1 in Hg. Determine the absolute pressure in the tanlk. Take $\rho_{\text{Hg}}$= 848.4 lbm/ft^3. Answer: 64.3 psia

A 3-kg plastic tank that has a volume of 0.2 m^3 is filled with liquid water. Assuming the density of water is 1000 kg/m^3, determine the weight of the combined system.

A tiny steel cube is suspended in water by a string. If the lengths of the sides of the cube are very small, how would you compare the magnitudes of the pressures on the top, bottom, and side surfaces of the cube?

Tell whether the following statements are always, sometimes, or never true. If a statement is not always true, explain. Rational numbers are integers.

A vacuum gage connected to a tank reads 45 kPa at a location where the barometric reading is 755 mmHg. Determine the absolute pressure in the tank. Take $ho Hg = 13,590 kg/m^3.$
