The paper concerns numerical study of fully developed laminar flow of a Newtonian, water and non-Newtonian fluids, 0.2% aqueous of sodium carboxymethyl cellulose(CMC) solution in concentric and eccentric annuli with combined bulk axial flow and inner cylinder rotation. Pressure losses and skin friction coefficients have been measured when the inner cylinder rotates at the speed of 0~200 rpm. The influences of rotation, radius ratio and working fluid on the annular flow field are investigated.

In order to fundamentally improve the productivity and safety of construction in preparation for population decline and aging, and to secure global competitiveness, innovation in construction technology is necessary. The Korean government also announced I-KOREA 4.0 as a national plan to respond to the 4th industrial revolution (4th Industrial Revolution Committee), and proposed a target of 40% improvement in construction productivity such as 3D virtual construction and intelligent construction equipment. Innovation has been selected and presented as an intelligent innovation project. As such, the construction industry cannot be an exception to the flow of the 4th industrial revolution.

Regarding the necessity of expansion of greywater supply and mandatory use, the use of graywater system is also desirable from the environmental point of view of recycling of water. The installation of greywater can be a countermeasure to solve the water shortage by preventing the waste of water in general buildings, factories and homes, It is possible to reduce the sewage generation amount by the amount of greywater consumption by the better quality water treatment.
