Here, there is a human powered submarine. The length of the submarine is 4.85 m and the hope is it can travel fully submerged through water at 0.440 m/s. The water it is being tested in is freshwater at a Temperature of 15 degrees celcius. The submarine model is built on a 1/5 scale and is built in a wind tunnel. A shield surrounds the drag balance strut so that the aerodynamic drag of the strut itself does not influence the measured drag. Here, the wind in the wind tunnel is at 25°C and at one standard atm pressure. What air speed is needed to run the wind tunnel in order to achieve similarity?

In April 2010, the worst oil spill ever recorded occurred when an explosion and fire on the Deepwater Horizon offshore oil-drilling rig left 11 workers dead and began releasing oil into the Gulf of Mexico. One of the attempts to contain the spill involved pumping drilling mud into the well to balance the pressure of escaping oil against a column of fluid (the mud) having a density significantly higher than those of seawater and oil.In the following problems, you may assume that seawater has a specific gravity of 1.03 and that a hypothetical subsea wellhead is 7167 ft below the surface of the Gulf. Gauge Pressure Estimate the gauge pressure (psig) in the Gulf at a depth of 7167 ft. ______psig

2. A student team is to design a human-powered submarine for a design competition. The overall length of the prototype submarine is 4.85 m, and its student designers hope that it can travel fully submerged through water at 0.440 m/s. The water is freshwater (a lake) at T = 15 °C. The design team builds a one-fifth scale model to test in their university's wind tunnel, as shown in the Fig. A shield surrounds the drag balance strut so that the aerodynamic drag of the strut itself does not influence the measured drag. The air in the wind tunnel is at 25 °C and at one standard atmosphere pressure. At what air speed do they need to run the wind tunnel in order to achieve similarity? Take for water at T = 15 °C and atmospheric pressure, p = 999.1 kg/m³ and µ = 1.138 × 10-³ Pa.s. Take for air at T = 25 °C and atmospheric pressure, p = 1.184 kg/m³ and µ = 1.849 × 10-³ Pa.s.

2. The apparatus shown below is designed to measure the density of an unknown fluid (p2₂). The two sides of the device are separated by a movable, frictionless partition. The partition is attached to the immobile sidewalls of the device via springs (different spring constants) on either side. Before pouring fluid into the device, both springs are unstretched. The device has a rectangular cross-section and extends a width w into the page. Derive an expression for the unknown density p2 = f(p1, h₁, h₂, k₁, k2, Ax, g), where Ar is the displacement of the partition relative to its equilibrium location before the fluids are poured into the apparatus. h₁ P1 k₁ 5 P2 ли Ax k₂ h₂
. I am planning to perform some volume-flow rate measurements in the Fluid Mechanics Laboratory. For this, I need a volumetric measuring tank (graduated cylinder) and a stopwatch. I considered the volume of the measured tank as 15 gallons and a stopwatch with reaction time as 1/10th of a second (though resolution of 1/1000th of a second). What is the volume flow rate if it takes 5 minutes to fill a 15-gallon of tank? Determine the smallest division to be on the tank in order to estimate the volume flow rate within an accuracy of ± 0.05 gpm.
Engineers are worried about the wind forces on a sculpture in Queen Mary campus. The sculpture has a height Ha = 5 m and a diameter, Da = 2 m, as shown in Figure Q3. The engineers decide to investigate making a smaller scale model testing in a water tunnel. They need to match the Reynolds number and the aspect ratio, AR = H/D. The characteristic length scale in the Reynolds number can be the diameter. Water has a density and viscosity of pw = 1000 kg/m3 and μw = 1 mPa. s, while air has a density and viscosity of pa = 1.2 kg/m3 and μa = 18 x 10-6 Pa. s. The average wind speed by the sculpture is Ua = 6 m/s. 1. The maximum height of the model that the engineers can place in the water tunnel is 1.5 m. Find the diameter of the model needed. 2. Find the average speed of water needed for the experiments to match the average wind speed past the sculpture. 3. It is known that at a wind speed of Ua = 4 m/s, the flow past the sculpture becomes turbulent. To visualise the flow in the experiments,…
