Flo’s Flow Woes Flo’s Flower shop has a frequently frustrating flow problem. Flo waters her greenhouse plants using a hose attached to a water tank on the roof. Unfortunately, Flo’s flow isn’t enough for her parched plants. 1. Flo first measures the flow she gets now by sticking the hose in a 50 gal drum and measuring how long it takes to fill. If it takes 25 minutes to fill the drum, what is Flo’s flow rate? (Remember: flow = volume / time)

Flo’s Flow Woes Flo’s Flower shop has a frequently frustrating flow problem. Flo runs grow lights all night. Unfortunately, Flo’s electrical flow (her electrical current) isn’t enough for her gloomy gladiolas. 2. Flo first measures the flow she gets now by sticking a meter on her power line and measuring how long it takes to store up 50 coulombs of charge. If it takes 0.25 seconds, what is Flo’s current? (Remember: current = charge / time and is measured in amps.)
