The laminar flow phenomena in the inlet (entrance) region of eireular pipe axe investigated experimentally. New curves of friction factor versus Reynolds number, for various entry lengths, are obtained and compared with the standard curve for fully developed laminar flow. The relationship between the viscous fricfion, the energy loss due to the lengthwise rate of change of the kinetic energy coefficient and the total energy loss is investigated. The continuous variation of the velocity profile is analysed by using the concept of a non-Newtonian liquid whose shear sensitivity varies continuously along the pipe.

The cell constant for the conductivity cell described in ref. 4 has since been carefully determined. This and other measurements concerning the true zero-charge conductivity are to be the subject of another manuscript.
This paper presents a numerical study of the transient developing laminar flow of a Newtonian incompressible fluid in a straight horizontal pipe oscillating around the vertical diameter at its entrance. The flow field is influenced by the tangential and Coriolis forces, which depend on the through-f
