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/(T₁-T₂) T₂/(T₁-T₂) T₂/R1 T₁/T₂ T₁/(T₁-T₂) T₂/(T₁-T₂) T₂/R1 T₁/T₂ ANSWER DOWNLOAD EXAMIANS APP
