Chemical Engineering Thermodynamics A reasonably general expression for vapour-liquid phase equilibrium at low to moderate pressure is Φi yi P = Yi xi fi° where, Φ is a vapor fugacity component, Yi is the liquid activity co-efficient and fi° is the fugacity of the pure component i. the Ki value (Yi = Ki xi) is therefore, in general a function of Temperature only Temperature, pressure and liquid composition xi only Temperature and pressure only Temperature, pressure, liquid composition xi and vapour composition yi Temperature only Temperature, pressure and liquid composition xi only Temperature and pressure only Temperature, pressure, liquid composition xi and vapour composition yi ANSWER DOWNLOAD EXAMIANS APP
Chemical Engineering Thermodynamics The efficiency of a Carnot heat engine operating between absolute temperatures T₁ and T₂ (when, T₁ > T₂) is given by (T₁ - T₂)/T₁. The co-efficient of performance (C.O.P.) of a Carnot heat pump operating between T₁ and T₂ is given by T₁/T₂ T₂/(T₁-T₂) T₁/(T₁-T₂) T₂/R1 T₁/T₂ T₂/(T₁-T₂) T₁/(T₁-T₂) T₂/R1 ANSWER DOWNLOAD EXAMIANS APP
