A 3 m long of flat surface made of 1 cm thick copper is exposed
to the flowing air at 30 °C. The plate is located outdoors to
maintain the surface temperature at 15 °C and is subjected to winds
at 25 km/h.Instead of flat plate, a cylindrical tank with 0.3 m
diameter and 1.5 m long was used to store iced water at 0 °C. Under
the same conditions as above, determine the heat transfer
rate, q (in W) to the iced water if air flowing
perpendicular to the cylinder. Assuming the entire surface of tank
to be at 0 °C
