Find the mean deviation of the set of numbers (a) 12, 6, 7, 3, 15, 10, 18,5
2 answers:
Answer:
4.25
Explanation:
The mean deviation is how far, on average, all values are from the middle. To do that, we subtract each element from the mean of the elements, take their absolute values, and then divide by the number of elements in the set. Here's the formula:
Here the mean is 9.5, the count n = 8, so the mean deviation is 4.25

Explanation:
Flow at entry is axial α₁ = 0
Tagential velocity at entry = 0
Blade at exit is radial β₂ = 0
μ₂ =
Answer:
W=-940.36 KJ
Explanation:
Given that
Process follows pv=constant
So this is the isothermal process and work in isothermal process given as
Now by putting the values (1.4 bar =140 KPa)
W=-940.36 KJ
Negative sign indicates that this is a compression process and work will given to the system.
