A circular tunnel discharging 0.56 cu. m./sec. needs repair at its invert. In order to undertake this work it will be necessary to isolate the area by means of two cofferdams, and pass the water through 18-in. steel pipes. If the difference in elevation between the water surface upstream of the cofferdam and the water surface downstream is 0.6 m., and the coefficients of head loss at the entrance and outlet of the pipe are 0.5 and 0.3, respectively, determine the number of pipes (use exact value shown by your calculation with 2 decimal points) needed to divert the discharge. Use f = 0.019. Length of pipe = 94 m. Round your answer to 2 decimal places.

1. Lines of levels are run from B11 to B12 over four different routes. BM12 is above BM11 and elevation of BM11 is 220 m above sea level. Compute the probable elevation of BM12 above sea level. 2. A sight is taken with an engineer’s level at rod held 80 m away and the reading was observed to be 2.81. The bubble is then leveled through five spaces on the level tube and the reading increased to 2.874 m. What is the radius of curvature of the level tube if each division is 0.6 mm?
