Abstract

The Bianchi type-III cosmological model in \(f(R,T)\) gravity is investigated with the equation of state for wet dark fluid, i.e., \(P_{\text{WDF}} = \omega (P_{\text{WDF}} - \rho^{*} )\). Using volumetric and power-law expansion, we obtained the exact solution of the field equations. The various astrophysical phenomena, namely, the look-back time, proper distance, luminosity distance, angular diameter, jerk parameter, and cosmic snap with red shift and state-finder parameters, are also discussed.
