1. Gasoline flows in a smooth pipe of 40-mm diameter at a rate of 0.001 m3 s. Show that the flow is turbulent. What would be the ratio of the head loss for the actual turbulent flow compared to that if it were laminar flow?
2. Air flows through the fine mesh gauze shown in Fig. P14.18 with an average velocity of 1.50 m/s in the pipe. Determine the loss coefficient for the gauze.
