###### A tube with radius 0f 1.1 cm and length 0f 5.3m has fluid of viscosity 0.002 Pa-s passing through it: The flow rate ofthe fluid through this tube is 0.0079 m3/s and you may assume the fluid flow aminar:The fluid is inserted into this tube by small pump; andthe fluid exits this tube into air; The tube horizontal, so the points where the fluid enters and exits the tube are atthe same height:What is the absolute pressure of the fluid where it enters the tube? Give your answer in units of Pa
