Question

When a gage pressure reading indicates 30 psi, what is the absolute pressure?

Answer 1

absolute pressure = 44.7 psi

Step-by-step explanation:

given data

gauge pressure = 30 psi

to find out

absolute pressure

solution

we consider here atmospheric pressure is 14.7 psi

so we know absolute pressure is sum of atmospheric pressure and gauge pressure

so

absolute pressure = atmospheric pressure + gauge pressure ........... 1

put here value

absolute pressure = 14.7 + 30

absolute pressure = 44.7 psi
