Question: The glass pipe system shown below has a liquid flowing in it at an unknown rate. The liquid is very corrosive and flow meters are

The glass pipe system shown below has a liquid flowing in it at an unknown rate. The liquid is very corrosive and flow meters are correspondingly very expensive. Instead you propose to your boss to add a fluorescent dye via a small pump and to deliver 1.00 g/s of this tracer and activate it by UV light. By monitoring the dye fluorescence downstream, you determine its concentration is 0.050 wt. %. What is the unknown flow rate in kg/hr? (This is a useful method of indirectly measuring flows.)
