Civil Engineering Questions & Answers

  Complete cycle of the motion

Find the time for one complete cycle of this motion if the spring constant is 21 N/m. (Assume that once the pendulum ball hits the spring there is no effect due to the vertical movement of the ball.)

  Seepage velocity and estimating hydraulic gradient

The dye appears 14 days later in an observation well 75 ft away from the injection point. Compute the seepage velocity and estimate the hydraulic gradient in the aquifer if the porosity of the soil is 42%.
