In thermal physics and thermodynamics, the heat capacity ratio, also known as the adiabatic index, the ratio of specific heats, or Laplace's coefficient, is the ratio of the heat capacity at constant pressure (CP) to heat capacity at constant volume (CV).

Psychrometrics can be used to predict changes in the environment when the amount of heat and/or moisture in the air changes. Use of psychrometric analysis is also important to determine the volume flow rates of air to be pushed into the ducting system and the sizing of the major system components.
26 mar 2024 · Sensible heat ratio (SHR) is the ratio between the sensible heat and the total heat. SHR is expressed in percentage and it is calculated by dividing the sensible heat by the total heat. SHR 80% means the sensible heat is 80% of the total heat while the other 20% is latent heat.
Online Air Specific Heat Calculator. The calculator below can be used to estimate the specific heat of air at constant volum or constant pressure and at given temperature and pressure. The output heat capacity is given as kJ/ (kmol*K), kJ/ (kg*K), kWh/ (kg*K), kcal/ (kg*K), Btu (IT)/ (mol*°R) and Btu (IT)/ (lb m *°R) Temperature.
