## Abstract The experimental results of singleβphase flow heat transfer and pressure drop experiments in the turbulent flow regime in a spirally ribbed tube and a smooth tube are presented in this paper. The ribbed tube has an outside diameter of 22βmm and an inside diameter of 11βmm (an equivalent
The pressure drop of boiling two-phase nitrogen flow in a smoo th horizontal tube has been studied experimentally. The results show in principle the well-known dependence of the Iocal pressure drop from the vapour quality, the mass flow rate, and the heat flux. A comparison of the measured friction
