Chemical Engineering Basics - Engineering
Q1: A thin, flat & square plate measuring 2 m x 2 m is freely hanging in ambient air at 25°C. It is exposed to the solar radiation falling on one side of the plate at the rate of 500 W/m2 . The plate temperature will remain constant at 30°C, if the convective heat transfer co-efficient is __________ W/m2 °C.A 50
B 100
C 150
D 200
ANS:B - 100 To determine the convective heat transfer coefficient (ℎh) required for the plate temperature to remain constant at 30°C when exposed to solar radiation, we can use Newton's law of cooling, which relates the rate of heat transfer (Q) to the temperature difference (ΔT) and the convective heat transfer coefficient (ℎh). The equation is: Q=hAΔT Where:
