A flat plate is insulated on the bottom and has air flowing across the top at a velocity of 5 m/s and a temperature of 20C. The plate is 1 m wide and extends 2 m into the page. Ignore radiation for now and determine the amount of heat power that must be provided to keep the plate surface temperature at 60C. (Air properties on next page) Air V=5 m/s T-20C 11111 L=1m The required convection heat power is If the air flow is stopped (V = 0) but the plate and air temperatures remained the same as the above figure, what amount of heat power would now be required to keep the 60C plate temperature? (Information on next page) The required convection heat power is T, 60C W W
