Question details

Question 3 120 Marks in Totall Determine the time constant for steady pressure to be developed in a circular 10um diameter steel micro-tube 3cm long, for water pumped using a 10mm diameter glass syringe in a syringe pump. where the syringe travel is 10% of the 150mm length of the syringe. [12 Marks] Comment on how long you should wait before assuming steady conditions. (3 Marks Suggest an alternative means to reduce compressibility effects, taking care to justify your suggestion. 15 Marks) HINT: using the following expression for the velocity distribution in the pump, where U is the piston velocity, develop a differential equation in terms of Pressure (P) 1 dP K di set the pressure datum to be zero at the outlet of the tube Take the following properties for water: Bulk Modulus K 2.2x10 N nr. Dynamic Viscosity 11 1.002 x 10 3 Pa s. Density ρ 1000 kg in?
