The flow rate of water in a garden hose is measured using the bucket-andstopwatch method. Filling a 5-L bucket takes 75 seconds. If the inner diameter of the hose is 10 mm and the density and viscosity of water are approximately 998 kg m-3 and 0.9 cP, respectively, (a) is the flow inside the hose laminar or turbulent? (b) If the flow rate is adjusted such that the flow is with Re = 2100, how long would it take to fill the same bucket?
Water is flowing in a horizontal smooth plastic pipe with a velocity of 20mm/s. What is the pressure difference between the point of entry to the exit of the 1m length of plastic pipe with a diameter of .15m if the dynamic viscosity is .0010016 Ns/m² ?
