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, determine the convection heat flux for (a) a vehicle speed of 40 km/h in air at -8°c with a convection coefficient of 40 w/m2. k and (b) a velocity of 0.2 m/s in a water stream at 10°c with a convection coefficient of 900 w/m2 k. which condition would feel colder? contrast these results with a heat flux of approximately 30 w/m2 under normal room conditions
