4 pengukuran tekanan
This document discusses pressure measurement. It defines pressure as force per unit area and discusses common pressure units like pascals, atmospheres, bars, and psi. It also describes different types of manometers that can be used to measure pressure, including U-tube manometers, Bourdon-tube gauges, barometers, bellows, diaphragms, capsules, and strain gauges. Manometers measure the pressure of contained gases using columns of liquid that vary in height depending on the pressure difference.
