For Problem 8. 1, find the minimum height H required to maintain a flow rate of 5 L/min if (a) the pipe is smooth, (b) pipe is made up of cast iron.

A swimming pool filled with water at 65°F is being emptied by gravity using a galvanized iron pipe of 3/4 in diameter and 20 fr length. Determine the depth of water level if the flow rate is 12 gal/ min.
