Answer: The complete part of the question is to find the exit velocity
Explanation:
Given the following parameters
Inlet pressure = 700kpa
outlet pressure = 40kpa
Temperature = 80°C = 353k
mass flow rate = 1 kg/s
The application of the continuity and the bernoulli's equation is employed to solve the problem.
The detailed steps and the appropriate formula is as shown in the attached file.
Answer:
The entropy change of the carbon dioxide is -0.1104 kJ/kg.K
Explanation:
We are given that carbon dioxide undergoes a process in a closed system.
We are asked to find the entropy change of the carbon dioxide with the assumption that the specific heats are constant.
The entropy change of the carbon dioxide is given by
Where Cp is the specific heat constant
Cp = 0.846 kJ/kg.K
R is the universal gas constant
R = 0.1889 kJ/kg.K
T₁ and T₂ is the initial and final temperature of carbon dioxide.
P₁ and P₂ is the initial and final pressure of carbon dioxide.
Therefore, the entropy change of the carbon dioxide is -0.1104 kJ/kg.K
