Consider an interesting scenario involving a data center on a particularly hot day where the ambient temperature rises to 29 degrees Celsius. Within the data center, a particular server is being kept at a cool 5 degrees Celsius to ensure optimal performance. The server has a height and width of 190 mm and 115 mm, respectively. For maintenance, the server has to be momentarily pulled out into the warmer ambient temperature for varying durations: 9 seconds, 55 seconds, and 290 seconds, before it is returned to its cooler environment. The heat transfer by natural convection on the server's sides is characterized by a convection coefficient of 12 W/mK, and the server's surface emissivity is 0.89. For the purposes of this exercise, assume the server's temperature remains steady at 5 degrees Celsius during the process. In the world of information technology, it's crucial to maintain low temperatures for servers to ensure their efficient performance and longevity. Taking this into account, assess the significance of promptly returning the server to its cooler environment from an energy efficiency perspective. Calculate the amount of heat transferred to the server during each time interval.
