2. (12 points) Water at a temperature of 50°F flows through a pipe of diameter D=0.73in. Determine the time taken to fill a 12-oz glass (volume = 0.0125 ft³) with water if the flow in the pipe is to be laminar (assuming Re=2000). Determine the time taken to fill the glass if the flow is to be turbulent (assuming Re=4000). Repeat the calculations if the water temperature is 140°F.
