A vertical unlined 22 ft diameter circular shaft is fitted with a concrete shaft liner to withstand water pressure of 123 psi in a massive sandstone aquifer at a depth of 2,890 ft. Liner properties are: E = 3.5 million psi, ν = 0.30, Co = 4,500 psi, To = 450 psi, γ = 152pcf. A liner safety factor of 3.85 is required in compression. Find the liner thickness (in.) and finished shaft diameter (ft).
