This paper focuses on temperature rise due to the viscous heating in liquids flowing through micro-channels. A correlation for the temperature rise has been obtained as a function of the friction factor, Reynolds number and Eckert number, starting from Navier-Stokes equations and energy equation under the assumption of fully developed flow. The temperature rise calculated from the correlation has been compared with experimental data and the correlation is validated. However, in this paper, a new correlation for the temperature rise is simply obtained from the first law of thermodynamics without limitation of fully developed flow.
