Importance of psychrometry
WitrynaFor any type of psychrometric process the rate of energy transfer to or from the air may be simply determined from the chart using the relationship Power (kW) = mass flow rate (kg/s) × enthalpy change (kJ/kg) = ṁΔh. So P = 0.75 × (66.0 – 40.5) = 19.1kW. This may be split into the power used to provide the sensible and latent cooling and ... Witryna17 sie 2015 · Studying psychrometry can provide students with real-world examples that help them better understand abstract thermodynamic concepts. BRIEF OVERVIEW OF PSYCHROMETRY FUNDAMENTALS Water evaporates when air touches its surface. Water vapor then exerts a force on that surface.
