SUMMARY
The discussion focuses on determining the flow type—laminar or turbulent—using the Reynolds number for water at 10°C flowing at 2 m/s in a 100-mm pipe. The calculated Reynolds number is 152671.8, indicating turbulent flow, as it exceeds the threshold of 4000. The method employed for calculation is correct, although attention to significant figures is advised for precision.
