a) For the thermal efficiency we have

With the previously values we know that
and
(convert the min to sec)
Replacing the values

b) We use the formula of carnot efficiency

**Note that apply the formula of carnot cycle we need to consider that there is no exchange of heat, there is no friction and the reservior are completely insulated
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) - A12 = A21 = 2.747
(b) - A12 = 2.148; A21 = 2.781
(c)- A12 = 2.781; A21 = 2.148
Explanation:
(a) - x1(a) = 0.1 | x2(a) = 0.9 | x1(b) = 0.9 | x2(b) = 0.1
LLE equations:
x2(a)*γ2(a) = x2(b)γ2(b)
(b) - x1(a) = 0.2 | x2(a) = 0.8 | x1(b) = 0.9 | x2(b) = 0.1
LLE equations:
x2(a)*γ2(a) = x2(b)γ2(b)
(c) - x1(a) = 0.1 | x2(a) = 0.9 | x1(b) = 0.8 | x2(b) = 0.2
LLE equations:
x2(a)*γ2(a) = x2(b)γ2(b)
