1a. An airplane has a mass of2.8×106 kgkg , and the air flows past thelower surface of the wings at 96 m/sm/s .If the wingshave a surface area of 1400 m2m2 , how fast must the airflow over the upper surface of the wing if the plane is to stay inthe air?
1b. Water at a gauge pressure of PPP =4.2 atmatm at street level flows into an office buildingat a speed of 0.82 m/sm/s through a pipe5.6 cmcm in diameter. The pipe tapers down to3.0 cmcm in diameter by the top floor,16 mm. Calculate the flow velocity in the pipe on the topfloor and Calculate the gauge pressure in the pipe on the topfloor.
1c. A fish tank has dimensions 30 cmcm wide by1.0 mm long by 0.60 mm high.If the filtershould process all the water in the tank once every 3.0 hh,what should the flow speed be in the 3.0-cmcm-diameter input tubefor the filter?
