Question

1.)Air in the Trachea (Points: 1) Air moves through the human trachea at 2.8 m/s during inhalation. Assume that a constriction in the bronchus exists at which the speed doubles. By what amount (in Pa) does the air pressure change as it flows through the constriction? Treat the air as an ideal fluid, and take the density of air to be 1.2 kg/m3. (Hint: does the pressure increase or decrease? Also, please give your answer in Pa.) 2.)Oil in a Pipe (Points: 1) A horizontal pipe of radius 50 cm and length 150 m carries oil (with viscosity 0.12 Ns/m2). At the end of the pipe, the flow rate is 55 m3/s and the pressure is atmospheric. What is the pressure at the beginning of the pipe? (Note: The final answer should be given in kPa.),I already submitted these questions. please look at the highlighed parts in the attachment, to see if the answer is right. 1.)Air in the Trachea (Points: 1) Air moves through the human trachea at 2.8 m/s during inhalation.

(Note: The final answer should be given in kPa.),The answers are not coverted to Pa for the first one and Kpa for the second one. Could you please convert them for me, I submitted the answers and they were both wrong. Please and thankyou I have to submit it in less than 2 hours,Hi No need to clarify. Thankyou
