Solution:

Given:

Pressure reading on Vacuum gauge = 4.8 psi

Atmospheric pressure = 12.5 psi

To find:

Absolute pressure in the chamber

Formula:

Absolute pressure = Gauge pressure + Atmospheric pressure

Calculation:

Substitute the given values in the above formula

Absolute pressure = 4.8 psi + 12.5 psi

Absolute pressure = 17.3 psi

Therefore, the absolute pressure in the chamber is 17.3 psi.

Hence, the correct option is (d) 7.7 psi.
