3) At a construction site, a site investigation has been carried out. At ground level (-1 m NAP) a clay layer with a thickness of 4 m is found (y = 16 kN/m”, k = 2.0x10-12 m/s, Cp = 15), followed by a sand layer of 6 m thickness (y = 20 kN/m², k = 5.0x10-7 m/s), another clay layer of 4m thickness (y = 18 kN/m3, k = 4.5x10-11 m/s, Cp = 25), and finally another sand layer (y...

7. The behaviour of lead in soil/water systems has been described in terms of Langmuir adsorption. From laboratory experiments using 'pure solids, the following values for Langmuir parameters have been estimated For clay b = 3200 L mol- Com = 4x10-4 mol g For organic matter b = 10 000 L mol-' Csm = 4x10-4 mol g -7 (a) Use these values to calculate the concentration (in mg L or ppb) of water-soluble lead in equilibrium with clay containing 5...

6 and 7 please explain
6. While cleaning out a laboratory, a chemist found an unlabeled gas cylinder containing 7.5 x 10 mL of gas at 20.5°C at 1.50 atm of pressure. The chemist believed the mystery gas could be pure He, Ne, Ar, or Kr. Towards this end, the gas was found to have a mass of 1.88 g. What is the molar mass? What is the most likely identity of the mystery gas? 7. Assuming all gas is...

7) (2.5 points) A model test is to be conducted in a water tunnel using a 1: 20 model of a submarine, which is to travel at a speed of 12 km/h deep under sea surface. The water temperature in the tunnel is maintained, so that is kinematic viscosity is half that of sea water. At what speed is the model test to be conducted to produce useful data for the prototype?

Question 6 It is required to construct a 4 m deep underground carpark in the heart of the city of Melbourne without disturbing the surrounding area. The required excavation for the proposed carpark and also the adjacent ground condition are shown in Figure 6.1. As can be seen from the figure, the adjacent ground consists of a 2 m deep clay deposit, resting on a 2 m thick sand deposit, where stable soil could be found below the sand deposit...
