circular tubes rectangular channelA microfluidic system is developed to study the response of cultured kidney cells to different drugs. The system is composed of long circular tubes for the injection of cell culture medium and drugs and removal of the waste samples along with a microfluidic channel with a rectangular cross-section for culturing cells.

Question 3: A microfluidic system is developed to study the response of cultured kidney cells to different drugs. The system is composed of long circular tubes for the injection of cell culture medium and drugs and removal of the waste samples along with a microfluidic channel with a rectangular cross-section for culturing cells. - The pressure difference along the two ends of the system is set to 60kPa. - The internal diameter and length of the tubes are 500m, and 40cm, respectively. - The width, height and length of the channel is 500m,50m, and 50mm, respectively. - The density and viscosity of cell culture medium/drug suspension is considered as 1000 kg/m3, and 1.25mPa.s, respectively. a. Calculate the flow rate of the cell culture medium/drug suspension through the system. (12.5 marks) b. Calculate the pressure drop along the tube. (7.5 marks) c. Calculate the pressure drop along the microfluidic channel. (10 marks)
