For the data in Problem 10.8, compute the length required to achieve the enlargement for each cone angle. Then compute the energy loss due to friction in that length using the velocity, diameter, and Reynolds number for the midpoint between the ends of the enlargement. Use water at 60°F.

Data from Problem 10.8.

Compute the energy loss for gradual enlargements with cone angles from 2° to 60° in the increments shown in Fig. 10.5 . For each case, water at 60°F is flowing at 85 gal/min in a 2-in Schedule 40 steel pipe that enlarges to a 6-in Schedule 40 pipe.
