The pressure at a point in a pipeline is 80 kPa. Assuming standard atmospheric pressure, the absolute pressure in the pipeline is most nearly:

Explanation:

The pressure you measure on a pipeline is generally a gauge pressure, this is the difference between the pressure inside the pipe and the atmospheric pressure.

In order to find the absolute pressure, we need to add the pressure in the atmosphere to the measured pressure, so we get:

the 101.325kPa is the equivalent to 1atm, so we get:

sure does
