Air flows across a 20-cm-square plate with a velocity of 5 my/s. Free-stream conditions are 10:C and 0.2 atm. A heater in the plate surface furishes a constant heat-flux condition at the wall so that the average wall temperature is 100-C. Calculate the surface heat flux and the value of h at an x position of 10 em.
