Determine the convection heat transfer coefficient (in W/m²-K) for air flowing at a velocity of 3 m/s in a 10-cm diameter and 10-m long tube. Air enters the tube at 10°C and leaves at 20°c, i.e. air is heated. Take the property of air at 1 atm and assume flow to be fully developed.

Question
Determine the convection heat transfer coefficient (in W/m2-K) for air flowing at a velocity of 3 m/s in a 10-cm diameter and 10-m long tube. Air enters the tube at 10°C and leaves at 20°C, i.e. air is heated. Take the property of air at 1 atm and assume flow to be fully developed. For air at 1 atm: Temperature k, W/m-K v, m?/s Pr 15°C 0.02476 1.470x10-5 0.7323 20°C 0.02514 1.516×10-5 0.7309 25°C 0.02551 1.562x105 0.7296
