AN INTRODUCTION TO Static Pressure

The pressure drop of an air filter is found by measuring the pressure on each side of the filter, then by subtracting the two pressures to find the pressure difference. Example: drill a test hole on each side of a filter, and measure the pressure in each test hole. Say the pressure before the filter measures 0.11 in. wc and the pressure after
