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:
90
Explanation:
mean is basically taking the sum of all numbers and then dividing the sum with the number of all given numbers..
here, the mean is 9, total numbers are 10.. so the sum will be 9 multiplied by 10, that is 90.
