Answer:
t = 27.5
Explanation:
Well to solve for t we need to combine like terms and seperate t.
So 3+5= 8
8 - 220t = 0
We do +220 to both sides
8 = 220t
And now we divide 220 by 8 which is 27.5
Hence, t = 27.5
Explanation:
It is known that energy balance relation is as follows.
Also,
so,
According to the ideal gas equation,
Putting the values into the above equation as follows.
=
= 693.3 R
Now, we will convert the temperature into degree Fahrenheit as follows.
693.3 - 458.67
=
From table A-
= 0.240 Btu/lbm R and
= 0.171 Btu/lbm
Now, we will substitute the energy balance as follows.
=
= 59.3 Btu
Thus, we can conclude that final temperature of air is 59.3 Btu.
Answer:
12,608 kPa
Explanation:
First we need to convert the density to standard units, that is kg/m^3
0.85 g/cm^3 = 0.85 × = 0.85 × 1000 = 850 kg/m^3
Pressure of oil = pressure at surface + rho × g × h
= 101,000 + (850×9.81×1500)
= 12,608 kPa
The units in the part 'rho.g.h' will cancel out against each other and you will be left with the unit Pascals - which is the unit for pressure.
Hope that answers the question, have a great day!
