Abstract

In this paper we consider a metric with hyperscaling violation on black brane background. In this background we calculate the ratio of shear viscosity to entropy density with hydrodynamics information. The calculation of this quantity lead us to constraint θ\theta as 3θ<43\leq\theta<4, and θ0\theta\leq0. In that case we show that the quantity of ηs\frac{\eta}{s} not dependent to hyperscaling violation parameter θ.\theta. Our results about ratio of shear viscosity to entropy density in direct of QCDQCD point of view agree with other works in literature as 1/4π1/4\pi.
