A person weighs 180 lb on earth where acceleration due to gravity is 32.2 ft/s². What is their mass in slugs? In kg? If the person has an average density similar to water, what is their volume? Answer: m = 5.59 slug m = 81.6 kg V = 0.08 m³

A boat floating in fresh water displaces 35.6kN of water. The weight of the water is 35.6 kN and its density is 1000 kg/m3. Would the volume of water displaced change? If so, how much?

1-53 The water in a tank is pressurized by air, and the pres- sure is measured by a multifluid manometer as shown in Fig. PI-53. Determine the gage pressure of air in the tank if h = 0.2 m, h, = 0.3 m, and h, = 0.46 m. Take the densities of water, oil, and mercury to be 1000 kg/m'. 850 kg/m, and 13.600 kg/m, respectively.
