Refrigeration and Air Conditioning The C.O.P. of an absorption type refrigerator is given by (where T₁ = Temperature at which the working substance receives heat, T₂ = Temperature of cooling water, and T₃ = Evaporator temperature) [T₁ (T₂ - T₃)] / [T₃ (T₁ - T₂)] [T₃ (T₂ - T₃)] / [T₁ (T₁ - T₂)] [T₃ (T₁ - T₂)]/ [T₁ (T₂ - T₃)] [T₁ (T₁ - T₂)] / [T₃ (T₂ - T₃)] [T₁ (T₂ - T₃)] / [T₃ (T₁ - T₂)] [T₃ (T₂ - T₃)] / [T₁ (T₁ - T₂)] [T₃ (T₁ - T₂)]/ [T₁ (T₂ - T₃)] [T₁ (T₁ - T₂)] / [T₃ (T₂ - T₃)] ANSWER DOWNLOAD EXAMIANS APP
Refrigeration and Air Conditioning On the pressure-enthalpy diagram, condensation and desuperheating is represented by a horizontal line because the process Takes place at constant temperature Involves no change in volume Takes place at constant entropy Takes place at constant pressure Takes place at constant temperature Involves no change in volume Takes place at constant entropy Takes place at constant pressure ANSWER DOWNLOAD EXAMIANS APP
Refrigeration and Air Conditioning The total pressure exerted by the mixture of air and water vapour is equal to the sum of pressures which each constituent would exert, if it occupied the same space by itself. This statement is called Kinetic theory of gases Dalton's law of partial pressures Newton's law of gases Avogadro's hypothesis Kinetic theory of gases Dalton's law of partial pressures Newton's law of gases Avogadro's hypothesis ANSWER DOWNLOAD EXAMIANS APP
