Answer:
21.81 %
Explanation:
given,
$600 up to $800 3
800 up to 1,000 7
$1,000 up to $1,200 11
$1,200 up to $1,400 12
$1,400 up to $1,600 40
$1,600 up to $1,800 24
$1,800 up to $2,000 9
$2,000 up to $2,200 4
Total = 3 + 7 + 11 + 12 + 40 + 24 + 9 + 4 = 110
the frequency of $1,600 to $1800
=
=21.81 %
Answer:
The work done is 1050 Btu
Solution:
As per the question:
Mass of steam, M = 15 lbm
Temperature, T =
Temperature, T' =
Pressure, P = 350 psia
Since, the process results in the change in volume at constant pressure.
Now, work done by the steam is given by;
W =
And
U = mV
So,
W =
W = (1)
Now, using the super heated vapor table:
At 350 psia and , V =
At 350 psia and , V' =
Now, using these values in eqn(1):
W =
