Q3: Air flows across a 20-cm-square plate with a velocity of $ m/s. Free-stream conditions are 10-C and 0.2 atm. A heater in the plate surface furnishes 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 cm. Answers: Q= 1414 W, b= 13.3 Wm?.C Q3: Air flows across a 20-cm-square plate with a velocity of 5 m/s. Free-stream conditionsare 10 C and 0.2 atm. A heater in the plate surface furnishes a constant heat-flux condition atthe wall so that the average wall temperature is 100 C. Calculate the surface heat flux and thevalue of h at an x position of 10 cm.Answers: Q= 1414 W, h= 13.3 W/m2.C
