Question B1 Water at room temperature (density p-1000 kg/m³ and viscosity -1.12x10 N.s/m²) is pumped from a reservoir and flows at a flow rate of Q-60 L/min through a 20 mm-diameter copper (roughness ks-0.015 mm) tubing system with a sharp-edged entrance and exits through a faucet of diameter 10 mm, as shown in Fig. B1. The tubing system has three 90° threaded elbows. The globe valve and faucet are fully open and the water level in the reservoir is maintained constant during operation. 3.0 m 3.0 m Sharp-edged Entrance 90° Elbow Fully open globe valve Fully open facet, the 5.0 m diameter of the exit is 10.0 mm 90° Elbow The same type of tubing is used. The diameter of all tubing is 20mm. The diameter of the faucet exit is 10mm. The water reservoir is maintained at a constant water level during operation.
