Air flows through a circular duct with a diameter of 8 cm at room temperature. the gauge pressure readings for the total pressure and the static pressure are 200 pa and 70 pa, respectively. assume that this system is in a room that is at a pressure of 100,000 pa and a temperature that is 300k. a. what is the velocity of the air in this 8 cm diameter duct. give your answer in m/s. b. furthermore downstream, the diameter of the duct decreases to 4 cm. what is the new velocity of the air when the diameter is 4 cm? give your answer in m/s.
