Saponification is a process wherein soap is added to a certain type of oil to produce grease. One such grease is said to have 75.7 % by volume oil and 24.3% by volume soap, wherein the oil and soap have densities 760 kgm/m3 and 6,250 kgm/m3, respectively. This kind of grease is sold by packs shaped like a sphere with a diameter of 20 cm for convenience. Calculate: a) the mass of oil per pack (kgm), b) the mass of soap per pack (kgm), c) the weight of each pack (kgf), d) the specific weight of grease (N/m3), e) will the grease float if it is placed in water whose density is 1000 kgm/m3? Explain.
A solar energy storage compartment contains 1,778 rocks that can approximate 3-inch-diameter spheres. The properties of the rocks are k = 2.2 Btu / h ∙ ft ∙ ºF, α = 0.07 ft2 / h, cp = 0.2 Btu / lbm ° F, and the density is 160 lbm / ft3. How long (in hours) would it take for solar energy to saturate the compartment using 200 ° F air from a solar collector? How much energy (in Btu) is stored in the compartment under these conditions if it is initially at 79 ° F and h = 5 Btu / h ∙ ft2 ∙ ºF?
