RESUMO

This is an investigation of non isothermal and non newtonian laminar flow in the entrance region of tubes. The flow is steady, incompressible and tube wall has constant temperature. Heating and cooling are considered. Experimental work was conducted using solutions of Xantan and Guar gums which exhibited pseudoplastic, as behaviour determined in a concentric cylinder rheometer. Power law fitted well the Theological behaviour of all fluids and temperature dependence between consistency index was of the exponencial type. Experiments lie in the ranges: 2x10-04
