The in situ stress at a point in a dry sandstone terrain is as follows: σ₁ = 12 MPa and σ₃ = 4 MPa. The pore water pressure (pᵥ) increases by the construction of a reservoir. The failure criterion of the sandstone is given by σ₁′ = 3.48 MPa + 3σ₃′, where σ₁′ and σ₃′ are the effective maximum and minimum principal stresses, respectively. Assuming that the failure occurs at peak stress, the minimum value of pᵥ (in MPa) that will cause the sandstone to fail in situ is _________ (rounded off to two decimal places).
