In theory, a cargo pump should be able to draw up a liquid to a height equaling atmospheric pressure. This would be approximately ___?
Direct Answer
Option D: 10 meters
Atmospheric pressure exerts approximately 101.3 kPa at sea level, which theoretically supports a water column of 10.33 meters. In centrifugal cargo pumps on oil tankers, cavitation and vapor pressure further limit practical suction lift, making 10 meters the standard theoretical limit referenced in ISGOTT guidelines.
