OK i need help. Please help me work thorought this with autocad. I am not sure where to begin but i need to draw this. Well if you read the question we did it in class and I got suepr confsued.
A square column foundation has to carry a gross allowable load of 2005 kN (FS = 3). Given: D₤ = 1.7 m, y = 15.9 kN/m³, 0' = 34°, and c' = 0. Use Terzaghi's equation to determine the size of the foundation (B). Assume general shear failure. For o' = 34°, N₁
36.5 and Ny = 38.04.

Fluid enters the suction line from reservoir 1 (left) through a sharp-edged inlet. The suction line is 10 cm commercial steel pipe, 15 m long. Flow passes through a pump with efficiency of 76%. Flow is discharged from the pump into a 5 cm line, through a fully open globe valve and a standard smooth threaded 90° elbow before reaching a long, straight discharge line. The discharge line is 5 cm commercial steel pipe, 200 m long. Flow then passes a second standard smooth threaded 90° elbow before discharging through a sharp-edged exit to reservoir 2 (right). Pipe lengths between the pump and valve, and connecting the second elbow to the exit are negligibly short compared to the suction and discharge lines. Volumes of reservoirs 1 and 2 are large compared to volumes extracted or supplied by the suction and discharge lines.
