Final answer:
By setting up a proportion based on the given data points, we can calculate the molar flow rate of the humidified air solution to be 154.375 lbmole/h.
Step-by-step explanation:
To estimate the molar flow rate of the humidified air solution, we need to use the calibration data for the flow meter. The calibration data states that a flow meter reading of r=15 corresponds to a flow rate of v'=40.0 ft3/h, and a flow meter reading of r=50 corresponds to a flow rate of v'=96.9 ft3/h. We can use these data points to calculate the molar flow rate of the humidified air solution by setting up a proportion.
First, we calculate the difference in flow meter readings: 50-15 = 35.
Then, we calculate the difference in flow rates: 96.9-40.0 = 56.9.
Next, we calculate the flow rate per flow meter reading: 56.9/35 = 1.625.
Finally, we can use the flow rate per flow meter reading to calculate the molar flow rate of the humidified air solution:
molar flow rate = 1.625 * 95 = 154.375 lbmole/h.
