WebThe constant C p tells how much enthalpy varies when the temperature changes by 1 K at constant pressure; in other words d H = C p d T. Since a temperature variation of 1 K is the same as a variation of 1 ° C, you can express it indifferently in k J / ( k g. K) or in k J / ( k g. ° C). Now, at first approximation, this C p is a constant. WebEngineering Chemical Engineering Estimate the change in enthalpy and entropy when liquid ammonia at 270 K is com- pressed from its saturation pressure of 381 kPa to 1200 kPa.

WebJan 30, 2024 · When you state: "Secondly, for an ideal gas, the internal energy and enthalpy are functions only of temperature, and do not depend on volume or pressure. So, for an ideal gas, irrespective of process path, we always have that" (and then you present the equations) why does that statement imply the equations you then provide? WebSpecific Enthalpy is a measure of the total energy in a unit mass. The SI-unit commonly used is J/kg or kJ/kg. The term relates to the total energy due to both pressure and temperature of a fluid (such as water or steam) at any given time and condition. More specifically enthalpy is the sum of internal energy and work done by applied pressure.
