PSYCHROMETRIC PROPERTIES & PSYCHROMETRIC CHART CLASS NOTES Psychrometry is the study of the properties of moist air (dry air + water vapor). It includes the study of psychrometric chart and Psychrometric processes. This chart contains psychrometric (moist air) properties. Use psychrometric processes to achieve desired conditions from the existing room conditions. It is quite easy…
PROPERTIES OF STEAM CLASS NOTES FOR MECHANICAL ENGINEERING Specific properties are per kg. Examples are specific volume, specific values of enthalpy, entropy, internal energy and latent heat. Symbol Small alphabets represent specific properties. Firstly specific volume =v Secondly specific enthalpy = h Thirdly specific entropy = s Fourthly specific internal energy =u Specific heat =cP…
MECHANICAL PROPERTIES CLASS NOTES FOR MECHANICAL ENGINEERING Materials/machines/structures are subjected to forces of one kind or the other or combined forces. How the materials behave under these forces is explained in terms of mechanical properties. Measure mechanical properties by various destructive tests. Various worth mentioning mechanical properties are (i) Ductility (ii) Elasticity (iii) Resilience…
THERMODYNAMIC PROCESSES AND PROPERTIES CLASS NOTES Any thermodynamic system works on a closed repeatable cycle. Each cycle consists of four processes. In these processes, there is transfer of heat and work into the system or out of the system. Normally processes have one variable as constant. Adiabatic process in which there is no heat…
