A flue gas is cooled from 950°C to 150°C, and the heat is used to generate saturated steam at 100°C in a boiler. The flue gas has a heat capacity given by CR = 3.83 +0.000551 T/K Water enters the boiler at 100°C and is vaporized at this temperature; its latent heat of vaporization is 2256.9 kJ-kg-¹. Take R= 8.314 J-mol K-1 NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. With reference to a surroundings temperature of 25°C, what is the lost work of this process in kJ-mol-1 of flue gas? The lost work of this process is 6.866 kJ-mol-1.

Question
Transcribed Image Text:A flue gas is cooled from 950°C to 150°C, and the heat is used to generate saturated steam at 100°C in a boiler. The flue
gas has a heat capacity given by
Cp = 3.83 +0.000551 T/K
R
Water enters the boiler at 100°C and is vaporized at this temperature; its latent heat of vaporization is 2256.9 kJ-kg-¹1. Take
R= 8.314 J-mol 1.K-1.
NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part.
With reference to a surroundings temperature of 25°C, what is the lost work of this process in kJ-mol of flue gas?
The lost work of this process is 6.866 kJ-mol-1
