1. Rainwater runoff from a parking lot flows through a 3-ftdiameter pipe, completely filling it. Whether flow in a pipe is laminar or turbulent depends on the value of the Reynolds number. Would you expect the flow to be laminar or turbulent? Support your answer with appropriate calculations.
2. Carbon dioxide at 20C and a pressure of 550 kPa (abs) flows in a pipe at a rate of 0.04 N/s. Determine the maximum diameter allowed if the flow is to be turbulent.
