Question

If the atmospheric pressure is 108.2 kPa and the gage attached to the tank reads 192 mmHg vacuum, find the absolute pressure within the tank.

Answer 1

Answer

Absolute Pressure = Gauge pressure + Atmospheric Pressure.

Where

$192mmHg=25.5979kPa$

atmospheric pressure is 108.2 kPa

So absolutele pressure

$=108.2kPa+25.5979kPa\\=133.7979kPa$
