A simple flow system to be used for steady flow tests consists of a constant head tank connected to a length of 4-mmdiameter tubing as shown in Fig. P6.79. The liquid has a viscosity of 0.015. s/m² and a density of 1200 kg/m³ and discharges into the atmosphere with a mean velocity of 1 m/s. (a) Verify that the flow will be laminar. (b) The flow is fully developed in the last 3 m of the tube. What is the pressure at the pressure gage? (c) What is the magnitude of the wall shearing stress, in the fully developed region?
