Example Problem 1

A 60-cm tall coffee urn is filled to the top. It dispenses coffee through a 0.7-cm diameter nozzle that is 12 cm above the table surface. How long does it take to pour a 200-mL cup of coffee?

Example Problem 2

A pitot-static tube is placed on the nose of a plane travelling 100 m/s at an elevation of 4000 m. What is the pressure difference between a point far away and the nose of the plane?  Assume density of air = 0.8194 kg/m3 at an elevation of 4000 m.
