cpa=specificheatofdryair=1.005kJ/kgK (1.12)h1=1.005t Similarly, the sensible heat of the moisture content h2 is given by: h2=gcpst−0 where: cpa=specificheatofwatervapour=1.89kJ/kgK (1.13)h2=1.89gt The water vapour is considered to have evaporated at 0°C, and therefore the latent he...
The authors have proposed a concept of "specific relative humidity" and given out the accurate formulae for calculating the thermophysical properties of moist air in a wide range. On the bases of this concept and these formulae, a generalized enthalpy-humidity chart which may be applied at diff...

This method is based on an empirical formula developed by James (1966). For highly productive two-phase geothermal wells, the James method is the most versatile and economical method of testing. Although not quite as accurate as the separator method, the lip pressure method has the advantages ...
If we have the enthalpy values for the formation of reactants and products, we can calculate the enthalpy change for the reaction using the formula:ΔHR=ΣΔHf(products)−ΣΔHf(reactants)where ΔHf is the standard enthalpy of formation. Step 6: ConclusionThus, Hess's Law is applicable...
The method comprises the following steps of: substituting all or some measured value of each measurement system of the device into a refrigerating capacity computing formula, so that not only can the technical index of each measurement system be respectively evaluated, but also the refrigerating ...
the most effective modification is simply by including the Rayleigh Pitot pressure formula to account for the static pressure recovered from a normal shock at the stagnation point [6]. An excellent affinity with numerical solutions by the solutions of the compressible Navier-Stokes equations has clear...
