Imagine we shape 0.3x103 kg of solid steel into a small boat model which can displace 0.8 m3 of water at its maximum capacity. What is the additional buoyant force we get from this ship compared to the buoyant force we would get by submerging this chunk of solid steel directly into water, in unit of N? ρ(steel) = 7.8x103kg/m3. ρ(water) = 1.0x103kg/m3. Use g = 9.8 m/s2.

You place a sphere of radius R=1.54 m and of density ρ = 0.75g/cm^3 in a pool of clean water. The sphere begins to float and a portion of the sphere begins to show. What is the height of the portion that shows above the water? What minimum force should you press on the sphere to make it sink completely in the pool? Show your complete work step by step.

A 3-m-internal-diameter spherical tank made of 1-cm-thick stainless steel is used to store iced water at 0°C. The tank is located outdoors at 18°C. Assume the entire steel tank to be at 0°C and thus the thermal resistance of the tank to be negligible. The heat of fusion of water at atmospheric pressure is hif = 333.7 kJ/kg. The emissivity of the outer surface of the tank is 0.75, and the convection heat transfer coefficient on the outer surface can...

A steel hot-water tank of cylindrical shape has an inside diameter of 0.600 m and inside height of 1.40 m. The tank is enclosed by a 5.00 cm thick insulating layer of glass wool whose thermal conductivity is 0.0350 W / (m·K). The insulation is covered by a thin sheet metal skin. The steel tank and the sheet metal skin have thermal conductivities that are much greater than that of the glass wool. How much electrical power (W) must be...

A block of wood, with density 780.0 kg/m^3, has a cubic shape with sides 0.272 m long. A cord of negligible mass is used to tie a piece of lead to the bottom of the wood. The lead pulls the wood into the water until it is just completely covered with water. What is the mass of the lead? Density of water is 1.00 × 103 kg/m^3 and density of lead is 11.3 × 103 kg/m^3.

A 1 m outer diameter spherical tank made of AISI 304 steel with 10 cm wall thickness contains solid iced water at 0°C. Air at 25°C flows outside the tank with a velocity of 1 m/s. Determine the rate of heat transfer to the tank and the mass rate ( m_dot) at which ice melts. Ignore convection effects of the melting ice. The latent heat of fusion of water at 0°C is 333.7 kJ/kg.
