## Pressure Vessel Force and Pressure
Force can be described in pounds or tons. We intuitively think of force in weight which is a fair description. Is there a difference between 10-psi and 1000-psi? Yes, there is a 100-times difference in pounds. This becomes very important when a pressure vessel contains steam, air, volatile gases, compressible gas/fluid, or substances that have internal energy such that when exposed to the atmosphere the substance expands violently. Steam is a good example where there is an expansion process of 1604-times [saturated steam].
A) 10-psi B) 10,000-pounds C) 1,131-pounds D) 101-pounds
That is over 1/2-ton of force with only
10-psi. The point here is 10-psi can be as deadly as 1000--psi. Finally,
we can never under estimate the care needed in keeping pressure vessels in
top condition. Force = 10-psi x p r
A.) 0-psi B.) 22-psi C.) 25-psi D.) 53-psi
Gradually, as we come down the tank wall the
pressure increases; therefore, the thickness of the tank wall would have to
increase in order to retain the water. p = g x 50-feet [don’t forget to
convert & g = 62.4 lbs../ft ## Next: Pressure Vessels >> |
