| Abstract: | The field equation for a viscous magnetohydrodynamic fluid satisfying an appro -priate set of thermodynamic relations is investigated. It is shown that Einstein-de Sitter model can be exact solution to this system of equations. The solution in which the spacelike component of the tilting velocity vector is radially directed is discussed. The solution presented satisfies all the necessary conditions for physical acceptability. |
