- Consider the three cases shown below, in which a soil column is subjected to different water heads (similar set-upDarby’s experiment in the reader). Using the tables provided, establish the pressure, elevation, and total heads ateach location, considering that the datum is:a) at the headwater, andb) at the tailwater.c) What was the effect of assuming a different datum on the i) pressure, ii) elevation, and iii) total heads?d) In the schematic for each case, draw an arrow indicating the direction of water flow inside the soil.e) What is the hydraulic gradient across the soil in each case?f) If the soil permeability and cross-sectional area of the cylinder remains constant across the different cases, whichone leads to the largest flow rate q? Which one has the lowest flow rate?g) What assumptions were necessary for you to answer these questions?arrow_forwardFor given distributed loads, see figures below, determine resultant and moments around load ends (points A and B). Assume p = 2kN/m.arrow_forwardA permeability test apparatus of diameter 82.5 mm contains a column of fine sand 460 mm long. When water flows through it under a constant head at a rate of 191 cm3/minute, the loss of head between two points 250 mm apart is 380 mm. Calculate the coefficient of permeability of the fine sand. If falling head test is made on the same sample using a standpipe of diameter of 30 mm, in what time will the water level in standpipe fall from 1560 mm to 1066 mm above outflow level.arrow_forward

They are designed to get you out of your classroom or office and develop the skills of designing experiments and collecting data, and then performing calculations, evaluating the results, and communicating your findings. Labs are more than just number crunching - they are about reflecting on what is both practical and technically sound engineering problem-solving. For each problem below, address the scenario presented and develop engineering solutions. Communicate your results using drawings, pictures, and discussion, supported by calculations developed using the Microsoft Equation Editor or similar tool. Submit your lab report in a single pdf file uploaded to the location provided in Canvas before the due date/time indicated. Each problem should be treated as a micro-report with a problem…arrow_forwardHow can a construction estimator gain experience to better judge appropriate contingency amounts?arrow_forward
