A Pitot tube is used to measure the velocity of an airstream at 20°C and 1.0 atm. If the velocity is 2.5 m/s, what is the dynamic pressure in newtons per square meter? What is the uncertainty of the velocity measurement if the dynamic pressure is measured with a manometer having an uncertainty of 5 Pa?
