Tiana Conley · Answer 1

38.6 kPa.

Explanation:

Liquids cavitate when the pressure falls below their vapor pressure for the temperature they are.

Water at 160F has a vapor pressure of:

pv = 38.6 kPa

So the minimum absolute pressure that can develop without causing cavitation would be just above 38.6 kPa.
