A loaded Airbus A380-800 aircraft with a mass of 520 tons flies in the air. The wing area of the aircraft is 841 M². Determine the mean pressure difference between the lower and upper sides of the aircraft wings.’ You must design a hydraulic jack (see picture). Its large piston should be able to lift 3 tons when the force on the small piston is F = 200N. The diameter of the large piston is determined by the customer to 7cm. Determine the diameter of the small piston. The pressure on the property's roof is 0.993 × 105 Pa. On the ground the temperature is the same as on the roof and the pressure is 1,010 × 105 Pa. The air density is 1.29 kg / m3. How high is the property? A metal block with a volume of 0.02 m3 and density = 6000 kg / m3 hangs under water (ρ = 1000 kg / m3). Determine the voltage T in the wire. Assume that the container has oil (density = 800 kg / m3) instead of water. Decide if the tension in the thread will then be greater, smaller or unchanged (an answer without motivation gives no points). A gas tube with a volume of 10 liters contains air under a pressure of 200 bar and a temperature of 25 ° C must be used in diving at a depth of 20 m where the water temperature is 5 ° C. How many liters of air does the tube hold under the conditions of diving? Consider two identical containers. Container A is filled with water up to a certain level. Container B has a wooden block floating on water there, but the water level in B is the same as in A. Which of the containers weighs more? Motivate your answer! A U-shaped tube is open to the atmosphere on both sides. The tube contains two different liquids. One has the density = 1000 kg / m3. The density of the other is 1 = 1200 kg / m3. The height h is 0.30 m (see figure). What is the height h1? Pelle floats in seawater with 90% of his body volume below the water surface. The density of seawater is 1025 kg / m3. Determine the average density of Pelle's body. During his lab exercise, Jens measured that the density of a piece of wood was. The analysis of his results showed that the accuracy of the measurement was approx. Before the summer, you will build a fleet of the same type of wood that Jens measured in the lab. The fleet must be able to float in water with you, three friends, a tent and other equipment totaling 600kg (including people). To be able to do this without too great risks for the fleet's rollover, the fleet must not start to sink before it is loaded with at least 2600 kg. How much should the fleet itself weigh?
