Introduction to Chemical Engineering and Thermodynamics

Express the volume expansivity and the isothermal compressibility as functions of density $\rho$ and its partialderivatives.For water at $323.15 \mathrm{K}\left(50^{\circ} \mathrm{C}\right)$ and 1 bar, $\mathrm{K}=44.18 \times 10^{-6}$ bar $^{-1}$. To what pressure must water be compressed at $323.15 \mathrm{K}\left(50^{\circ} \mathrm{C}\right)$ to change its density by $1 \%$ ? Assume that $\kappa$ is independent of $\mathbf{P}$.

Introduction to Chemical Engineering and Thermodynamics

Generally, volume expansivity $\beta$ and isothermal compressibility $\kappa$ depend on $\mathrm{T}$ and $\mathrm{P}$. Prove that:
$$\left(\frac{\partial \beta}{\partial P}\right)_{T}=-\left(\frac{\partial \kappa}{\partial T}\right)_{P}$$

Introduction to Chemical Engineering and Thermodynamics

The Tait equation for liquids is written for an isotherm as:
$$V=V_{0}\left(1-\frac{A P}{B+P}\right)$$
where $V$ is molar or specific volume, $V_{0}$ is the hypothetical molar or specific volume at zero pressure, and $\mathrm{A}$ and $\mathrm{B}$ are positiveconstants. Find an expressionfor the isothermal compressibility consistent with this equation.

Introduction to Chemical Engineering and Thermodynamics

For liquid water the isothermal compressibility is given by:
$$\kappa=\frac{c}{V(P+b)}$$
where $c$ and $b$ are functions of temperature only. If 1 kg of water is compressed isothermally and reversibly from 1 to 500 bar at $333.15 \mathrm{K}\left(60^{\circ} \mathrm{C}\right)$, how much work is required? At $333.15 \mathrm{K}\left(60^{\circ} \mathrm{C}\right), \mathrm{b}=2700 \mathrm{bar}$ and $\mathrm{c}=0.125 \mathrm{cm}^{3} \mathrm{g}^{-1}$.

Calculate the reversible work done in compressing $0.0283 \mathrm{m}^{3}$ of mercury at a constant temperature of $273.15 \mathrm{K}\left(\mathrm{O}^{\circ} \mathrm{C}\right)$ from 1 atm to 3000 atm. The isothermal compressibility of mercury at $273.15 \mathrm{K}\left(0^{\circ} \mathrm{C}\right)$ is
$$\kappa=3.9 \times 10^{-6}-0.1 \times 10^{-9} P$$
where $P$ is in atm and $\mathrm{K}$ is in $\mathrm{atm}^{-1}$.

A small cruising ship that can hold up to 72 people provides three-day excursions to groups of 44 or more. If the group contains 44 people, each person pays $66. The cost per person for all members of the party is reduced by $1 for each person in excess of 44. Find the size of the group that maximizes income for the owners of the ship.
