Answer: freemasonry is Being a Mason is about a father helping his son make better decisions; a business leader striving to bring morality to the workplace; a thoughtful man learning to work through tough issues in his life.
Explanation:
Answer:
[a]. 0.49.
[2]. 0.536
[c]. 4.15 kmol; 5.84 kmol.
Explanation:
Without mincing words let's dive straight into the solution to the question above.
[a].
The initial external reflux ratio, LD that must be used = [(0.85 - 0.57)/ 0.85 - 0]/ [ 1 - (0.85 - 0.57)/ 0.85 - 0].
The initial external reflux ratio, LD that must be used = 0.329/ 1- 0.329 = 0.49.
[b].
The final external reflux ratio that must be used = [ 0.85 - 0.13/ 0.85 - 0]/ [ 1 - 0.85 - 0.13/ 0.85 - 0].
Hence, the final external reflux ratio that must be used =0.847/ 1 - 0.847 = 5.536.
[c].
The amount of distillate product that is withdrawn:
4 = 0.85 H(t) + 0.8 - 0.08.
H(t) = 4.15 kmol, and the value of Wfinal = 5.84 kmol.
Answer:
0.163 MW
Explanation:
To get the minimum rate of energy rehection by heat transfer to cold reservoir, it implies that the power cycle operates in reversible cycle. The efficiency of reversible cycle whose value will be same as efficiency of power cycle will be given by
Efficiency of reversible cycle
n= (Th-Tc)/Th where T represent temperature, n efficiency, subscripts h and c hot and cold respectively
Substituting 500 and 310 for hot and cold temperatures respectively then efficiency
n=(500-310)/500=0.38
Efficiency of power cycle, n= Power output/Qh
Qh= 0.1/0.38= 0.263
Net power output, W= Qh- Qc
Qc=Qh-W= 0.263-0.1=0.163 MW
