A pretensioned 48-inch inside diameter reinforced concrete pipe similar in con-
figuration to that of Problem 8.22 is manufactured using a 10 gage (0.1345 inch) steel
cylinder wrapped with 0.244-inch diameter steel wire on 1.00-inch centers. The total wall
thickness of the pipe is 5.0 inches with a 3.00-inch cement-mortar lining. The cement
liner has a 28-day strength of 6000 lb/in2. Assuming the gasket joints act as expansion
joints, calculate the wave speed for the pipe.
