Astream of humid air containing 2.50 mol% h2o(v) and the balance dry air is to be humidified to a water content of 9.00 mole% h2o. for this purpose, liquid water is fed through a flowmeter and evaporated into the air stream. the flowmeter reading, r, is 95.0. 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 v = 44.0 ft /h and v = 98.9 ft/h, respectively. water flow estimate the flow rate of the liquid water feed if the volumetric flow rate is a linear function of r. v= i ! ft3/h - i ib-mole/h . estimate the flow rate of the liquid water feed if the reading ris a linear function of v ft3/h- i ib-mole/h
