What do you mean by term hydraulic conductivity? What are the factors which effect the hydraulic conductivity?

An open top vertical standpipe 12 ft in diameter and 50 ft tall contains water with a specific weight of62.4 lb/ft^3. The wall thickness of the vessel is 0.5 in. What is the axial stress in the bottom of the tank? Please answer in kPa

Mia, Mikes’ little sister, plays in a sandbox. She wants to make a huge sand cake in the shape of truncated cone of height 1 ft. The low base should have radius 2 ft, and the upper base - radius 1 ft. How much work should Mia put on this project? The density of the sand is 100 lb/ft3, acceleration due to gravity is 32 ft/s2, and Mia constructs the cake taking the sand from the ground. Solve the problem along the following lines: (a) On the truncated cone, show the given dimensions. Draw a typical thin horizontal layer, introduce variables, and determine the dimensions of the layer. (b) For this layer, determine the volume, mass, weight, and work required to lift the sand to the level of the layer. (c) Set up the integral for the total work and calculate this integral. You are not allowed to use integral calculators, but you may use a calculator to multiply numbers.

The bottom of a river is 37 ft. below the water surface, Underneath the bottom of the river is a layer of silt which has a specific gravity of 1.79. If a pressure of 77 lb.per sq. in. is recorded at a tunnel at the bottom of the silt layer, how thick is this layer of silt in ft. ?   Round your answer to 2 decimal places.
