Abstract
A five dimensional Kaluza-Klein space-time is considered in the presence of perfect fluid source in a scalar-tensor theory of gravitation proposed by Brans and Dicke (Phys. Rev. 124:925, 1961). A cosmological model with a negative constant deceleration parameter is presented using a relation between the metric potentials and an equation of state. The model obtained can be considered as a five dimensional radiating universe in this theory. Some physical and kinematical properties of the model are also discussed.
