**How does pressure affect enthalpy? Socratic**

The specific enthalpy of the fluid inside the pressure vessel is the same as the specific enthalpy of the fluid as it escapes from the valve. With a knowledge of the specific enthalpy of the fluid, and the pressure outside the pressure vessel, it is possible to determine the t... Specific Enthalpy Specific enthalpy (h) is defined as h=u+PÎ½, where u is the specific internal energy (Btu/lbm) of the system being studied, P is the pressure of the system (lbf/ft 2 ), and Î½ is the specific volume (ft 3 /lbm) of the system.

The total enthalpy of the air comprises of the sensible heat and the latent heat. The enthalpy scale in the psychrometric chart is located outside the main body. The constant enthalpy lines extend from the enthalpy scale down toward the right side of the chart. To find the value of the enthalpy of the any given air, one should know its WB temperature. The constant enthalpy line passing through... where mass flow rate and h is specific enthalpy. From a calculation viewpoint alone, the power calculation is particularly sensitive to the specification of flow rate, inlet temperature and â€¦

Since heat is path dependent, however, we must specify the process, i.e., the path, to find . Two useful processes are constant pressure and constant volume, so we will consider these each in turn. We will call the specific heat at constant pressure , and that at constant volume , or and per unit mass.... 11/04/2006Â Â· Homework Help: Specific enthalpy of air Apr 11 I'm sure this is a really dumb question, but how do you find the specific enthalopy of air at a given temp and pressure? I Have been using my thermo tables for everything but I do not have tables for air. The only tables for air that I see list the properties at .1 Mpa and I need it at 200, and 90kPa. Do I use Cp?

**Internal Energy Enthalpy and Specific Heats of Ideal Gas**

My company is interested in finding the effectiveness of an air conditioning system by measuring the change in enthalpy from one side to the other. As a software person, I need a formula that I can use to calculate the enthalpy. I know this formula would need to include different properties of the gas, can you elaborate on what those constants are? Thank you very much.... Cp is "Specific Heat in constant pressure".This means it is the amount of heat required to increase temperature by 1 dgree celcius, when heat is given at constant pressure.where as...Cv is "Specific heat in constant volume". This means it is the amount of heat required to increase temperature by 1 dgree celcius, when heat is given at constant volume.

- Enthalpy measures the total energy of a thermodynamic system - either in the form of heat or volume multiplied by pressure. It is a state function, depending only on the equilibrium state of a system.
