With the following data, answer the following table: Cylinder (Al) Length (cm) Diameter Air Water (gr) Alcohol (gr) (cm) (gr) 1.3 1.88 9.82 6.36 6.83 2 2.63 1.87 19.68 12.59 13.47 3.83 1.87 28.98 18.43 19.73 5.09 1.88 38.47 24.4 26.15 5 7.83 1.92 64.28 41.99 43.27 Cylinder (Al) % of mistake Specific density of solid (water) Theoretical solid (water) specific density 2 3 Cylinder (Al) Specific density of solid (alcohol) Theoretical solid % of mistake (alcohol) specific density 2 3 4In 1923, the United States Army (there was no United States Air Force at that time) set a record for in-flight refueling of airplanes. Using two refueling planes, an Airco DH-4B biplane was able to remain in flight for 35 h. During the flight, the refueling planes were able to air-transfer a total of 687 gallons of fuel to the plane in 9 refueling transfers. Assume that the refueling nozzle had a diameter of 1.65 in and each refueling took 2.43 min to perform. Calculate the velocity of the fuel through the nozzle. Assume that the fuel filled the entire cross-sectional area of the nozzle. velocity: 12.94 m/s IncorrectLikuid petroleum exerts a presure of 2.60 kPa on a circular face of a piston with a radiusr = 1.90 cm. What is the total force on the piston?
- A simple thermometer is formed by taking a large spherical container of volume 1.13m³ and filling it with an ideal gas. Then, a U-shaped tube is attached that is very narrow so that very little fluid/gas can fit inside the tube. The tube has a small quantity of a fluid of density 1200kg/m³ placed in it. In equilibrium at room temperature - 21.9°C - the height of the fluid on both sides of the U-shaped tube are level. This is illustrated in the image below. What is the temperature of the gas in the spherical container when the left side of the fluid is 13.25cm higher than the right side of the fluid in the U-shaped tube? Atmospheric pressure is 101000Pa. °Cssm A patient recovering from surgery is being given fluid intravenously.
