To use a thermodynamic graph, locate the fluid s initial state on the graph. (For a saturated fluid, this point lies either on the saturated liquid or on the saturated vapor curve, at a pressure py) Read the enthalpy hy volume v, and entropy from the graph. If thermodynamic tables are used, interpolate these values from the tables. Calculate the specific internal energy in the initial state , with Eq. (6.3.23). 

N.B. The larger value of s is always used as the numerator so that the value of / is always greater than unity. The value obtained for F is then checked for its significance against values in the /-table calculated from an /-distribution (Appendix 13) corresponding to the numbers of degrees of freedom for the two sets of data.

What is its molecular formula (c) Using the atomic molar masses from the periodic table, calculate a more accurate molar mass of the compound. 

Radioactive 22Na was coated onto a glass sample that was made into a diffusion couple (Fig. 5.2) and heated for 4 h at 411°C. The radioactivity perpendicular to the surface is given in the following table. Calculate the tracer diffusion coefficient, D, of 22Na in the glass. 

Radioactive 180 was diffused into a poly crystalline pellet of ZnO at 900°C for 48 h. The diffusion profile had a marked tail showing that extensive grain boundary diffusion had occurred. The variation of the concentration of the radioactive isotope with depth for the tail of the penetration profile is given in the following table. Calculate the grain boundary diffusion coefficient, Dgb, of 180 if the bulk diffusion coefficient at 900°C is 5.53 x 10-21 m2 s-1 and the grain boundary width is taken as 1 nm. 

Given the following heat of reaction and the bond energies listed in the accompanying table, calculate the energy of the C=0 bond. All numerical values are in kilocalories per mole, and all substances are in the gas phase. 

The Log-Rank Test as presented by Peto et al. (1977) uses the product-limit life-table calculations rather than the actuarial estimators shown above. The distinction is unlikely to be of practical importance unless the grouping intervals are very coarse. 

The higher prices of cars, which is balanced by subsidies, has two impacts in ASTRA first, car manufacturers increase their revenues and output, compared with BAU, and second, a few other sectors that manufacture significant shares of the fuel cell also benefit. HyWays estimates that about one third of a car s price is related to the drive train. For hydrogen-fuel-cell cars, out of this one third about 30% is assumed to be provided by the chemical sector and 40% by the electronics sector in ASTRA. The remaining 30% is still manufactured by the vehicle sector. Hence, the according shares of demand for H2 fuel-cell vehicles are shifted from the vehicles sector, which before produced 100% of the drive train, to the chemicals and electronics sectors, respectively. This affects the sectoral final demand and the input-output table calculations in ASTRA. 

The variation of QJ/i) with ft may be computed easily from equation (17.7) when /< > 1. Tables calculated in this way are contained in the volume quoted at the end or 13. The following Fig. 7, which was prepared from these tables, shows the variation of Qn(, ) with ft for a few values of >2.

Because of the explosive development of computer sciences, the number of software programs and packages has increased dramatically. Tab. 1-3 presents a list of some programs and software packages for table calculation, and methods of basic and advanced statistics. It is clear that in such a booming market, only a relatively subjective overview can be given.

As shown by Eq. (10), Aal is a multiplicative ( normalization ) factor that allows one to relate the experimental quantity Ky to the order parameter S. For each experimental T value listed in your table, calculate An( T) from Eq. (12) and K T) from Eq. (11). Then use your best value for Aal to calculate a value of Sat each experimental T value and plot these 5(7) points versus T. The theoretical power-law curve for 5(7) given by Eq.

The two-part nomograph presented here estimates the electrical power generated at the alternator terminals. If the electrical power is known, the extracted or condensed steam flow in the turbine can be estimated. Estimation is quick and accurate it does not require aids such as the steam tables, calculators or personal computers. 

You are given the data in the table. Calculate the atomic mass by multiplying the mass of each isotope by its percent abundance and summing the results. Use the periodic table to confirm the calculation and identify the element. 

The homonuclear diatomic molecules are the simplest closed set of molecules. Many of the electron affinities of the main group diatomic molecules have been measured by anion photoelectron spectroscopy (PES), but only a few have been confirmed. These Ea can be examined by their systematic variation in the Periodic Table. Calculating Morse potential energy curves for the anions and comparing them with curves for isoelectronic species confirm experimental values. The homo-nuclear diatomic anions of Group IA, IB, VI, VII, and 3d elements and NO are examined first.
