Most combustion takes fundamenntos with air as the oxidizer, special cases do occur where a different oxidizer is used.

What does that imply for the real substance h and s values relative to ideal gas values? The kPa in Wyen B. There is not a B section table so use compressibility chart Table A. Moles are not conserved, what is conserved are the atoms so each atom in the reactants must be found in the products.

What is the absolute pressure at the bottom of the tank? Fuel cells are attractive for power generation because their direct output is electrical energy.

Linear interpolation between and K. Concept-Study Guide Problems Phase diagrams General Tables Ideal Gas Compressibility Factor, Review Problems Correspondence table The correspondence between the problem set in this sixth edition versus the problem set in the 5’th edition text.

At this state the piston is 0. Now it is cooled to ,10 C. Yes mass is conserved as we do not consider the quantum physic effect of mass and energy conversion.

A compressibility factor that is greater than one comes from domination of intermolecular termodianmica of repulsion short range over forces of attraction long range — either high temperature or very high density.

Most equations of state are developed to cover the gaseous phase, from low to moderate densities. What do you need to know if it is a gas phase? It takes place at a rapid rate, due to fundamentox driving forces, and results in stable products of combustion that have little fundamemtos no tendency to return to their former constituents and states. The heating value is the negative of the enthalpy of combustion.

Oxygen diffuses in from the air and the fuel evaporates from the wick.

For a liquid or solid, v is much more sensitive to Termodinzmica than P. Is that mixture rich or lean? To cover a wider region the EOS must be more complex and usually has many terms so it is only useful on a computer.

From the definition and variation in Gibbs function, see Eq. The state is at so high P, T that the saturated liquid line is not extremely steep.

If the nitrogen content of air could be lowered will the adiabatic flame temperature increase or decrease?

Extend the curve a little into the single-phase region. Heavy molecules show up as yellow. Find the new pressure, and quality if saturated, if the volume doubles. How long time will it take before the methane becomes single phase and what is the pressure then?


The slope is the same at a given T regardless of v. However at very high P, the substance eventually must become a solid, which cannot be compressed to a volume approaching zero.

Find the final specific volume. For each location find the pressure and the change in specific volume v if: If I raise the pressure in an isothermal process does h go up or down for a liquid or solid? P, T Table B. It is actually difficult to determine the phase boundary from the EOS. Repeat the question for the case the volume is reduced to rundamentos the original volume.

P T Borgnakke and Sonntag A small table of P, T values were entered into a spreadsheet and a graph made as shown below.

The number of excess O2 is the same in reactants and products. To what pressure should it be expanded?

In the two-phase region, P is a function only of T, and not dependent on v. If I raise the pressure in an isentropic process, does h go up or down? Enviado por Thais flag Denunciar. Fenomenos de Transporte 2. It is necessary to know the critical pressure and temperature, as well as ideal-gas specific heat.
