Solution:
Given:
pressure ratio, 
= 6.75
Formula used:
(1)
where,
= pressure ratio
γ = specific heat ratio of a gas( here, helium gas it is 1.667)
Now,
Eqn (1 ) is for thermal efficiency of an ideal gas, using eqn (1), we get
\eta = 1- \frac{1}{2.1469} = 0.5342
percentage thermal efficiency, \eta =53.42%
Answer:
The time taken to achieve the 0.9 fractional conversion, t = 28.125 hours
Explanation:
The first image attached is the picture showing the question clearly.
The 2nd attached image is page 1 of the solution and the 3rd attached image is the page 3 of the solution.
Answer:The distinction between a permanent magnet and an electromagnet is essentially one in how the field is created, not the properties of the field afterwards. So electromagnets still have two poles, still attract ferromagnetic materials, and still have poles that repel other like poles and attract unlike poles.

#SPJ1
we have
x<5
x>c
we know that
The solution is the intersection of both solution sets of the given inequalities.
The solutions of the compound inequality must be solutions of both inequalities.
The value of c could be 5 or any number greater than 5, such that there are no solutions to the compound inequality
Because
A number cannot be both less than 5 and greater than 5 at the same time
therefore
the answer is
for c_> there are no solutions to the compound inequality
