A hot brass plate is having its upper surface cooled impinging jet of air at temperature of 15°C and cooled by heat transfer coefficient of 220 W/m2-K, Then 10 cm thick brass plate (p = 8530 kg/m3 cp =380 J/kg∙k = 110 W/m·K, and α = 33.9 × 10-6m2/s) had a uniform temperature of 650°C, and the 10 cm surface of the Plate is. insulated. Using a uniform nodal spacing of Δx = 2.5 cm determine (a) the explicit finite difference equations (b) the maximum allowable value of the time step, (c) the temperaturethe at the center plane of the brass plate after 1 minute of cooling and (d) compare the result in (c) with the approximate analytical solution from Chapter 4.
