EXAMPLES: 1  With 45 of suction pressure on the blower inlet and no discharge pressure on the blower discharge, the total static pressure = 50.3 inWG. 2  With 45 of suction pressure on the inlet and 12 of discharge pressure on the discharge, the total static pressure = 50.3+12 = 62.3 inWG.
Meth can stay in the system and be detected in urinalysis drug tests 1-4 days after use. But chronic use can extended this detection period. More here on how meth works and the length of time it stays in your system, with a section for your questions about meth at the end.
