Within the activities of the scientific and cultural activity of the second semester of the Department of Chemical Engineering at the University of Technology for the academic year 2017-2018, the student of the Master Elaf Khalid lecture entitled:

Improvement of Dray Raduction for Water Flow in Pipe Based Nano Fluid

 "Reducing the obstruction of fluid flow in pipes by adding nanomaterials"

Al Khwarizmi Hall in the department in the presence of the Head of Chemical Engineering Department. Jamal Mouna Ali Al-Rubaie and Scientific Assistants Dr.D. Khalid Ajmi Saker and Al-Adari A.D. Walaa Abdulhadi Nuri and a number of heads of branches and teachers and employees and students of the university.

     In this research, the student showed that several methods were used to reduce the high cost of energy used to transport fluids in pipelines. , Where recent studies have demonstrated the effect of nanotubes as a reduction in fluid flow. The aim of this study is to understand how the presence of solids or nanoparticles in liquids can reduce the problems of friction losses in pipes. This study investigated the effect of nanoparticles as mitigating factors for energy losses resulting from water transfer in pipelines. Where nanotubes are added at low concentrations such as parts per million to the solution. These small quantities played a dominant role in reducing disturbance and causing a significant reduction in friction losses. The tested water samples were selected, and nanotubes used for water and nanoparticles were used in five different concentrations (50-250 ppm) The experimental system consists of four different types of pipes (a 29.6 mm steel pipe, a 18.3 mm steel tube, a 29.6 mm glass tube, a 29.6 mm L pipe), water pumping at different flow rates (1.0 to 8.0) ) M3 / h for each type of pipe and at room temperature (35 ± 1) o. In addition, the effect of the type of nanoparticles such as silica SiO2 and TiO2 was also studied for comparison purposes.
