Problem 3 - The School or Aeronautics is doing some weather evaluations using a helium-filledspherical balloon with a radius of 12 inches. The balloon and associated instrumentation weigh0.1 lbf. Determine the terminal ascent velocity of the balloon if the air temperature is 60°F.The terminal ascent velocity is based on when the balloon's velocity is constant (no4VolumeπρSphere 3acceleration). The volume of the balloon iswhere r is the radius. Use atemperature of 60°F to determine the air properties. The problem is an iterative problem butlimit the number of iterations to 2 and make sure you explain the solution process and theequations required. Although not required creating a free-body diagram may make solving theproblem easier. Do not spend time trying to create the final numerical solution.

Aaerodynamics: An incompressible air is flowing at a velocity of 60 mph through a duct 4 sq. ft. in cross-section. The duct then decreases in area towards the throat section. If the instrument records a change of 8 inches of water, what is the area of the throat? Assume standard sea level conditions inside the tube.

A jet of water issues out from a fire hydrant nozzle fitted at a height of 3 m from the ground at an angle of 45 degrees with the horizontal. If the jet under a particular flow condition strikes the ground at a horizontal distance of—assume values with decimals between 15 to 20 m— m from the nozzle, find the jet velocity and the maximum height the jet can reach and its maximum horizontal distance from the nozzle. Neglect air resistance. Answer this will with complete solutions and figures. Thanks
On the mountain in Kalinga ,a mountain biker carried an aneroid barometer in his bike from base to top. On the ground level, the barometer read 35.12 in. Hg absolute; topside it read 26.807 in. hg absolute. Supposing that the average atmospheric air density was 0.075 lb/ft^3, estimate the height and slope distance of the mountain if the average slope angle is 32 degrees .
A venturi meter 45 cm by 20 cm has its axis inclined upward 30° from the horizontal. The distance measured along the axis, from the inlet to the throat is 1.20m. The differential manometer connected at the inlet throat shows deflection of 25cm of mercury. If the flow is upward and the blowing fluid has specific gravity of 2.0. Find the discharge and pressure head between the inlet and throat if the meter coefficient is 0.96.
