Question

Suppose the working pressure for a boiler is 10 psig, then what is the corresponding absolute pressure?

Answer 1

The corresponding absolute pressure of the boiler is 24.696 pounds per square inch.

Step-by-step explanation:

From Fluid Mechanics, we remember that absolute pressure (
`p_(abs)`), measured in pounds per square inch, is the sum of the atmospheric pressure and the working pressure (gauge pressure). That is:

`p_(abs) = p_(atm)+p_(g)` (1)

Where:

`p_(atm)` - Atmospheric pressure, measured in pounds per square inch.

`p_(g)` - Working pressured of the boiler (gauge pressure), measured in pounds per square inch.

If we suppose that
`p_(atm) = 14.696\,psi` and
`p_(g) = 10\,psi`, then the absolute pressure is:

`p_(abs) = 14.696\,psi+10\,psi`

`p_(abs) = 24.696\,psi`

The corresponding absolute pressure of the boiler is 24.696 pounds per square inch.
