In this paper, we are going to examine the spatially homogeneous and anisotropic LRS Bianchi type-I (B-I) Universe with viscous fluid in the framework of f (Q) symmetric teleparallel gravity (Phys. Rev. D 98.4 (2018): 044048). To solve the field equations, the following two hypotheses are proposed: (i) the relationship between the directional Hubble parameters i.e. Hx = nHy (where n = 0, 1 is an arbitrary real number) which is obtained from the proportionality relation between the expansion scalar θ and shear scalar σ 2 i.e. θ ∝ σ 2 , and (ii) the relationship between the average Hubble parameter H and bulk viscous coefficient i.e. ζ = ζ0 + ζ1H + ζ2. HH + H , where ζ0, ζ1 and ζ2 are constants. Some cosmological parameters such as the deceleration parameter, EoS parameter, skewness parameter, statefinder and Om(z) diagnostic parameters of the model are produced and evaluated through graphical representation. It was also confirmed that our f (Q) gravity model with bulk viscosity is consistent with recent observational data.
