Predicting Meter Readings

Predicting O2 meter reading: Known material has vp of 31 mmHg. Which of the following is the correct predicted O2 meter reading?

Predicting O2 readings: vp 15 mmHg Which of the following is the correct predicted O2 meter reading for this vapor pressure?

Predicting O2 readings: vp of 300 mmHg Which of the following is the correct predicted O2 meter reading for this vapor pressure?

LEL conversions to PPM review: LEL reading % times CF times PLEL% = ? ÷ 100 = ?% times 10,000 = ? PPM LEL % x CF x PLEL% = ? ÷ 100 = ?% x 10,000 = ? PPM 10% x 3.4x 4% = 136 ÷ 100 = 1.36% x 10,000 = 13,600 PPM

Predicting Lower Explosive Limit meter readings: Multiply the Conversion Factor (CF) times the Published Lower Explosive Limit (PLEL) times 100 = ? CF x PLEL x 100 = ? Divide ? into the maximum achievable PPM from the 1300 rule Example: Propenol's CF for LEL is 2.1%, PLEL is 2.5%, vapor pressure is 17mmHg vp [...]

LEL Meter Prediction: vp = 33 mmHg, LEL CF = 2.2, PLEL = 2.0% Which of the following is the correct predicted LEL meter reading for this material? 33 x 1300 = ? CF x PLEL x 100 = ? ? ÷ ? = predicted meter LEL reading

LEL Meter Prediction: Normal butyl alcohol (n-butanol) vp = 6 mmHg, PLEL = 1.4%, LEL CF = 2.8. Which of the following is the correct predicted LEL meter reading for n-butanol?

LEL Meter Predictions: Known chemical vp = 3 mmHg, PLEL = 1.2%, LEL CF = 2.5 (per manufacturer's spec's) Which of the following is the correct predicted LEL meter reading for this chemical?

Predicting PID, O2 and LEL Readings: PID formula for predicting is: vp x 1300 ÷ CF = ? O2 formula for predicting is: vp x 1,300 = ? ÷ 50,000 = O2 drop (20.9% - O2 drop) LEL formula for predicting is: (step #1) vp x 1300 = ? (step #2) CF x PLEL X [...]

Predicting PID, O2 and LEL Readings: PID formula for predicting is: vp x 1300 ÷ CF = ? O2 formula for predicting is: vp x 1,300 = ? ÷ 50,000 = O2 drop (20.9% – this O2 drop) LEL formula for predicting is: (step #1) vp x 1300 = ? (step #2) CF x PLEL [...]
