Consider a cylinder of 20 mm in diameter (d) and 100 mm in length (l) that is installed in a duct. air moves in cross flow over the side surface of the cylinder at a temperature (t∞) and velocity (v) of 33.7 °c and 30 m/s, respectively. if the average cylinder surface temperature (ts) is maintained at 120 °c, what is the required power generation of the cylinder? note: (1) air properties can be found from table a.4 in the textbook. (2) the heat loss from the top and bottom surface of the cylinder is negligible. (3) use churchill and bernstein method to solve it.
