本文提出了一种计算不可压缩牛顿流体等温层流在圆截面均匀圆管入口流动发展和压降的方法。就业的微分和积分动量方程导致更简单的表达比在其他理论治疗中发现，虽然获得的解决方案比较同样有利的有限的实验测量可用;本文报道的那些建议需要一个更广义的分析方法，其中包括非等温流动和流动发展的温度依赖性粘度的影响。
A method is described of predicting flow development and pressure drop in the inlet of a uniform pipe of circular cross-section for the incompressible isothermal laminar flow of a Newtonian fluid. Employment of both the differential and integral momentum equations leads to greater simplicity of expression than is found in other theoretical treatments, though the solutions obtained compare equally favourably with the limited experimental measurements available; those reported herein suggest the need for a more generalized analytical approach which covers non-isothermal flow and the effect on flow development of temperature-dependent viscosity.
