Exercise 10

Part 1

Why did Reynolds try experiments with different temperatures of water with each pipe?

Part 2

With the data from Exercise 9, calculate the Reynolds number at each radial distance. Note that the kinematic viscosity of water at 20 oC is approximately 1 centiStoke = 1×10−6 m2/s. You will need to multiply by 24×60×60 to convert m2/s to m2/day, 0.0864 m2/day. It is always important to pay attention to units and convert to consistent units when making calculations. Given that the pumping rate was given in m3/day, kinematic viscosity needs to be converted to length units of meters and time units of days. Which aquifers might have non-Darcian flow based on your calculations of average velocity?
