A thin flat plate 2m by 2m is hanging freely in air. The temperature of the surrounding is 25°C. Solar radiation is falling on one side of the plate at the rate of 500W/m2. The temperature of the plate will remain constant at 30°C if the convective heat transfer coefficient (in W/m2 °C) is:

Manufacturing engineering or production engineering is a branch of professional engineering that shares many common concepts and ideas with other fields of engineering such as mechanical, chemical, electrical, and industrial engineering.
