A stream of humid air containing 2.00 mol% H2O(v) and the balance dry air is to be humidified to a water content of 10.0 mole% H2O.
For this purpose, liquid water is fed through a flowmeter and evaporated into the air stream.
The flowmeter reading, R, is 105.0.
The only available calibration data for the flowmeter are two points scribbled on a sheet of paper, indicating that readings R = 21.0 and R = 54.0 correspond to flow rates Vā
= 42.0 ft3/h and Vā
= 100.9 ft3/h, respectively.
a) Estimate the flow rate of the liquid water feed if the volumetric flow rate is a linear function of R.
i) V= ft3/h
ii) n= lb-mole/h
b) Estimate the flow rate of the liquid water feed if the reading R is a linear function of V^0.5
i) V= ft3/h
ii) n= lb-mole/h
