Understanding Vacuum and Vacuum Measurement
solarmfg.comUnderstanding Vacuum and Vacuum Measurement Because of the work of 17th century scientist Evangelista Torricelli, we know that the atmosphere generally exerts enough pressure at sea level to support about a 30-inch (760mm) column of mercury. From that foundation, we can measure decreases in atmospheric pressure in
