Additional housing to accommodate 2000 persons is proposed for a residential area served by an existing 18-inch diameter vitrified clay sanitary sewer main constructed on a slope of 0.00412 ft/ft. To determine the feasibility of the proposed development, a 90° V-notch weir was placed in an existing manhole to measure the current flows. During peak hour flow conditions, the maximum head over the crest of the weir was measured at 16.5 inches. Note that the discharge over...

6. A 5-kg block is pressed against a spring near the bottom of a 30° inclined plane. The spring, (spring constant 450 N/m) is compressed by 0.50 m.When released, the spring projects the block toward the top of the incline. The coefficient of kinetic friction between the block and the inclined plane is 0.3. (a) What is the speed of the block at the instant the block first returns to its equilibrium length? ans [3.9 m/s] (b) Calculate the speed...
