Properties of Fluids

The term fluid represents a type of substance that can easily change its shape under any external pressure/force and can flow. Fluids can acquire any shape in which it is stored and can resist normal stresses but cannot resist shear stress in rest condition. Whenever external shear stress is applied to fluids, it starts to flow. The fluids may be liquid or gas. Example- water, air, etc.

A helium balloon is inflated to 1.08 bars (gauge) and released. It has a diameter of 0.3 m and can be assumed to be a smooth sphere. The mass of the latex balloon material is 3 g. The surrounding air is at 20°C. (a) Considering that the helium is pressurized, what is the density of the helium? (b) What is the total weight of the balloon including the helium and latex? (c) What is the magnitude of the buoyancy force? (d) What is the fastest upward velocity of the balloon? Don't account for elevation affecting the surrounding air properties.
Global warming will produce rising sea levels partly due to melting ice caps and partly due to the expansion of water as average ocean temperatures rise. To get some idea of the size of this effect, calculate the change in length, Ah (in mm), of a column of water 1.5 km high for a temperature increase of 1.2 °C.Assume the column is not free to expand sideways. As a model of the ocean, that is a reasonable approximation, as only parts of the ocean very close to the surface can expand sideways onto land, and only to a limited degree. As another approximation, neglect the fact that ocean warming is not uniform with depth. Properties of water: 3 = 210 x 10 /C. c= 4186 J/kg - °C, L; = 334 kJ/kg, Le = 2256 kJ/kg Enter you answer below (to the nearest mm): Ah (in mm) = Type your answer.
Timah Tasoh dam in Perlis has the dimensions of 20-m high and 770-m wide. It is filled with water of density equals to 1000 kg/m² and gravitational force equals to 9.81 m/s?. (a) The water from the dam is mixed with soap to make a soap solution and bubbles. When the bubbles are released into the air, they form nearly spherical shape. (i) Name the property of fluid that allow this situation to happen with its symbol. (ii) The soap bubble flew into the air and makes a diameter of 5 cm. If the surface tension of the soap solution in air at 1 atm and 20°C is 0.025 N/m, calculate the gauge pressure inside it. (iii) For a bigger diameter of 7 cm with the same soap solution parameters as in Question 1(a)(ii), determine the gauge pressure inside this new bubble. What can you derive from these differences and why?

A spherical weather balloon is filled with hydrogen until its radius is 3.10 m. Its total mass including the instruments it carries is 22.0 kg. (a) Find the buoyant force acting on the balloon, assuming the density of air is 1.29 kg/m3. kN(b) What is the net force acting on the balloon and its instruments after the balloon is released from the ground? kN(c) Why does the radius of the balloon tend to increase as it rises to higher altitude? Because the external pressure decreases or increases with increasing altitude.

An intrepid treasure-salvage group has discovered a steelbox, containing gold doubloons and other valuables, restingin 80 ft of seawater. They estimate the weight of thebox and treasure (in air) at 7000 lbf. Their plan is to attachthe box to a sturdy balloon, infl ated with air to 3 atm pressure.The empty balloon weighs 250 lbf. The box is 2 ftwide, 5 ft long, and 18 in high. What is the proper diameterof the balloon to ensure an upward lift force on the box thatis 20 percent more than required?
On October 21, 2001, Ian Ashpole of the United Kingdom achieved a record altitude of 3.35 km (11,000 ft) powered by 600 toy balloons filled with helium. Each filled balloon had a radius of about 0.47 m and an estimated mass of 0.32 kg. (a) Estimate the total buoyant force on the 600 balloons. (Enter your answer to at least two decimal places.) kN(b) Estimate the net upward force on all 600 balloons. kN(c) Ashpole parachuted to Earth after the balloons began to burst at the high altitude and the system lost buoyancy. Why did the balloons burst? Atmospheric pressure at this high or low altitude is much lower or higher than at the Earth's surface.
