Rock Haven has a proposed project that will generate sales of 1,815 units annually at a selling price of $29 each. The fixed costs are $16,400 and the variable costs per unit are $8.75. The project requires $32,200 of fixed assets that will be depreciated on a straight-line basis to a zero book value over the 4-year life of the project. The salvage value of the fixed assets is $8,300 and the tax rate is 35 percent. What is the operating cash flow? $9,941 $16,047 $24,500 $19,428 $10,412

Demonstrate that $Z_c$ can be written in terms of the Ursell-Mayer function $f(r) = e^{-U(r)/kT} - 1$ as $Z_c(T, V, N) = \frac{1}{V^N} \int d^3Nq \prod_{i<j} (1 + f_{ij}) = \frac{1}{V^N} \int d^3Nq \left( 1 + \sum_{i<j} f_{ij} + \sum_{i<j<k<l} f_{ij}f_{kl} + \sum_{i<j<k<l<m<n} f_{ij}f_{kl}f_{mn} + ... \right)$ where $f_{ij} = f(r_{ij})$. This expression is the starting point of the well known virial (or cluster) expansion², in terms of integrals of increasing order in $f$. Demonstrate that $\int d^3Nq f_{ij} = \int d^3Nq f(|q_j - q_i|) = V^{N-1} \int_0^{\infty} 4\pi r^2 f(r)$ and use it to show that³ $Z_c(T, V, N) = 1 + \frac{N^2}{2V} \int_0^{\infty} 4\pi r^2 f(r) + \frac{1}{V^N} \int d^3Nq \sum_{i<j<k<l} f_{ij}f_{kl} + ...$ (1) The advantage of this expansion is that it provides a systematic way to approximate the partition function for a non-ideal gas. The first term in the series corresponds to an ideal gas (no interatomic interactions), the second term is important when two-particle interactions are frequent, and higher order terms account for interactions involving more than two particles. For low densities, in which multiparticle interactions are not as likely as two-particle interactions, the first non-ideal correction comes from the second term in (1).
