The convection coefficient is an important thermal property. In this study, using an infrared thermometer, the convection coefficient of still air is estimated. First, the sample is heated in a sintering oven, then placed on a wood table for obtaining an almost adiabatic boundary, finally its temperature is recorded with respect to time using an infrared thermometer. The data is curve-fitted to find the sample temperature as a function of time. Using the sample’s physical dimensions, the specific heat capacity and the mass of the sample, the convection coefficient of still air is estimated.
