The reason for the flight of the aircraft is that it is driven by the airflow from the lower part of thewing. ( )2. Since the units on both sides of the hydrodynamic formula are required to be the same, thedimensions on both sides are also the same. ( )3. Euler's analysis method is to track the motion of a single particle in the fluid and obtain the lawof its motion. (O4. The pressure difference on the surface of a droplet can be obtained by the surface tension and theradius of the droplet Ap = Y/R. ()%3D5. According to the correlation between fluid flow and time, it can be divided into steady fluid andunsteady fluid. ( )6. When the center of gravity of the body is below the center of buoyancy, the body is in stableequilibrium. ( ) (Fill in the blank.1. In general, velocity V is a vector function of position and time, a lot of physical quantities aboutvelocity, their dimensions are:{Vdr, {r}=.(a) Displacement vector: r =(b) Acceleration: a =-dV/dt, {a}=.(c) Volume rate of flow: Q= [(V n)dA, {Q}=2. For non-Newtonian fluids, there are many complex physical phenomena:(а) Аor shear-thickening, fluid increases resistance with increasing applied stress.(b) Аor shear-thinning, fluid decreases resistance with increasing applied stress.(c) Fluids require a gradually increasing shear stress to maintain a constant strain rate and arecalled(d) Fluids require a gradually decreasing shear stress to maintain a constant strain rate and arecalled3. There are classic flow patterns:(а) Аis a line everywhere tangent to the velocity vector at a given instant.(b) Аis the actual path traversed by a given fluid particle.(c) Ais the locus of particles which have earlier passed through a prescribed point.

In the first second, it ejects 1/160 of its mass as exhaust gas and has an acceleration of 16.0 m/s2. What is vg, the speed of the exhaust gas relative to the rocket?
How much energy would it take to raise a can of soda (m = 350 grams) to average cruising altitude (35,000 ft)? Our textbook states that a gallon of gasoline contains 1.2×108 Joules of energy. Assuming 100% efficiency, how many gallons of gasoline would it take to raise the can of soda to 35,000 ft? A calorie is the amount of energy needed to raise the temperature of 1 gram of water by 1 Celsius degree (4.186 J). A nutritional Calorie is actually 1000 calories (1 Cal = 1 kcal). How many Calories of energy does it take to raise the can of soda to cruising altitude? Given that a can of Coke is about 140 Calories, how many cans of coke does it take to raise a can of coke to cruising altitude?
7. Saul ascends from the city of Tucson, Arizona to the top of Kitt Peak, 2900 m above the sea level. Usually, Saul will feel his ears “pop” as the pressure inside his ears attempts to maintain the equilibrium with the surrounding air. However, on this day Saul has cold and his Eustachian tube is clogged, causing a tremendous pressure behind his 4.0×10^(-5) m^2 ear drum. What force does Saul feel pushing on his ears? (D_air=1.20 kg/m^3) a. 0.50 N b. 0.05 N c. 0.12 N d. 0.08 N e. None of the above
