please explain step by step

Question 4 (15 pts) Suppose you are part of a team who is working on developing an artificial respiratory device for patients. At some point, you needed to estimate the power required for the inhalation of an average person. Using your fluid mechanics knowledge and with some additional assumptions, you should be able to determine. It is known that the tidal volume, which is the air breathed in with each normal breath through the mouth and nose (labeled as A), is 0.5 liters. If it occurs within 1.5 seconds through the trachea (labeled /S ) having a cross-sectional area of 125mm2, estimate the power required for a single inhalation. State any assumptions you are making. Hint: Recall that Power=(Force, F) (velocity, v)
