2. An orifice meter was calibrated for dry air at 7=90 °F and P = 1.3 atm. The calibration data are as follows: (4+4+4+5 points) AP, inches of water Q, ft³/minute 0 0 0.5 2.0 1.0 3.0 2.0 4.2 3.0 5.0 4.0 5.5 4.5 5.6 5.0 5.8 a. Plot the calibration curve for this meter. b. Derive a mathematical relationship describing the calibration curve. c. Calculate the volumetric flow rate when the meter reads 1.5 inches of water. d. Calculate the mass flow rate of air in g/min. 2. An orifice meter was calibrated for dry air at 7=90 °F and P = 1.3 atm.
