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.

Ithink they do have the same properties just in less quantities i think

Is a  vector quantity  that refers to "the rate at which an object changes its position." imagine a person moving rapidly - one step forward and one step back - always returning to the original starting position. while this might result in a frenzy of activity, it would result in a zero velocity. because the person always returns to the original position, the motion would never result in a change in position. since velocity is defined as the rate at which the position changes, this motion results in zero velocity. if a person in motion wishes to maximize their velocity, then that person must make every effort to maximize the amount that they are displaced from their original position. every step must go into moving that person further from where he or she started. for certain, the person should never change directions and begin to return to the starting position.
