1.A town requiring 2 cms ofwater has two sources, a local well with 15 g/m^3 of a contaminantand a distant surface water source with 2 g/m^3 of the contaminant.form the SDWA the contaminant can not be present at concenteration above 5 g/m^3. what flow rate are required from the local well andthe surface water?
2.For arectangular section (b(width) x h(thickness) that is subjected to a force P that is applied at an eccentricity (e) measured from the center of area of the rectangle in the h(thickness)direction. Find e in terms of b and h to have one type of normal stresses (that of a triangular distribution).
