A 1/2 cubic metre short boom dragline having ideal output of 150 m³/hr is to be used to excavate hard tough clay. The effect of the depth of cut of 5.0 m and angle of swing of 120° shall be 0.89. The operating factor shall be 50 min/hour. Determine the probable output of the dragline. Question:2 Calculate the time required to grade and finish 30 km of road formation of 9.0 m width for two-lane road with motor grader having width of 3.0 m, using six passes with speed for each of the successive two passes as 5 kmph, 7 kmph and 9 kmph respectively. Assume machine efficiency based on operator skill, machine characteristics and working conditions as 80%.

The peak discharge for a circular culvert was found to be 1.25 m^3/s. It has been determined that a water flow speed of 1.5 m/s is needed to maintain scour velocity. Calculate the approximate diameter of a circular culvert needed to carry the 1.25 m^3/s if the culvert is flowing at a depth 3/4 of the diameter. Assume that the flow in the culvert is not complex and water does not pond at either end of the culvert.
