摘要：

An experimental investigation of pressure drop and heat transfer for laminar and transitional flow of air was made. The effect of wall cooling or fluid heating on pressure drop is most significant within the transition region and depends, to a marked extent, on the magnitude of the heat input. For heat transfer, the Nusselt number is directly proportional to the square root of the Reynolds number. The experimental results of previous investigators support the 1/2 power dependence of the Nusselt number on the Reynolds number. Explicit relationships between laminar friction factor and heat transfer are established.
