A constant-head permeability test gives the following information: - Water flows horizontally through the soil sample. - The height of the reservoir supply source is 2 m above the elevation of the outlet reservoir. - The soil sample length in the direction of flow is 200 mm. - The cross-sectional area of the soil sample is 1,950 mm2. - The measured volume of flow at steady state is 500 ml in 10 minutes. a) Sketch the arrangement of the set up for this type of measurement. b) Calculate the hydraulic conductivity. c) Which is the probable tested soil

Agas contained within a piston-cylinder assembly e end nation about same energy states, 1 and 2, where pi 10 bar, v undergoes two processes, a and b, between the sam 0.1 m3, ui-400 kj and p2 1 bar, v2 1.0 m2, u2 200 kj: process a: process from 1 to 2 during which the pressure- volume relation is pv constant process b: constant-volume process from state 1 to a pressure of 2 bar, followed by a linear pressure-volume process to +20 0 state 2 kinetic and potential energy effects can be ignored. for each of the processes a and b, (a) sketch the process on p-v coordinates, (b) evaluate the work, in kj, and (c) evaluate process the heat transfer, in kj
