B. i A cell with radius of 5 um is initially is osmotic equilibrium with its surroundings at 300 mOsm and 25C. The cell is placed in a 155 mm solution of sodium chloride. a) Which way will water flow through the membrane and what is the initial flow rate if the filtration coefficient of the cell is 0.0004 um/mmHg/sec? (4 marks) b) Estimate the final cell volume. [1 mark) Blood flows through an extracorporeal device consisting of many hollow fibers arranged in parallel. Each fiber has an inside diameter of 75 um and length of 10 cm Plasma viscosity is 105 CP (1 CP = 0 001 Pa sec). A pressure difference of 50 mmHg (1 mmHg = 133 3 Pa) is applied across the fibers Viscosity of blood is 2.15 CP a) What will be the blood flow through a single fber? (2.5 marks) ii Page 6 of 11 b) The hollow fibers are used to oxygenate blood. How many fibers are needed to allow a flow rate of 100 ml/min through the device when the pressure difference across the fibers is 50 mmHg? (2.5 marks) A ovatb
