Question

Hot air at 80°C is blown over a 2 m x 4 m flat surface at 30°C. If the average convection
heat transfer coefficient is 55 W/m2 °C, then the rate of heat transfer from the air to the
plate is​

Answer 1

Answer:

Hot air at 80°c is blown over a 2-m x 4-m flat surface at 45°c. if the average convection heat transfer coefficient is 55 w/m2·k, determine the rate of heat transfer from the air to the plate, in kw.
