You've experienced convection cooling if you've ever extended your hand out the window of a moving vehicle or into a flowing water stream. With the surface of your hand at a temperature of 30°C, consider the two following conditions. Condition A: a vehicle speed of 35 km/h in air at -6°C with a convection coefficient of 40 W/m².K. Condition B: a velocity of 0.2 m/s in a water stream at 10°C with a convection coefficient of 500 W/m².K. What is the convection heat flux for the following? Condition A: 9 air = Condition B: qwater = W/m² W/m² C C M
