Consider a hemi-spherical tank with radius R = 16 see figure that is initially entirely filled with a fluid. At time t=0, the fluid begins to drain through an opening in the bottom of the tank see figure] until the tank is completely empty at t = tend- t= 0 te (0, tend) (a) At any time t, consider the maximum depth of fluid in the tank, h = h(t), and the corresponding radius of the surface of the fluid,...

Question 8 A tank of water has been outdoors in cold weather, and a slab of ice 3.9 cm thick has formed on its surface (see the figure). The air above the ice is at 13°C. Calculate the rate of formation of ice (in centimeters per hour) on the ice slab. Take the thermal conductivity of ice to be 0.0040 cal/s cm-C°, its density to be 0.92 g/cm3, and its latent heat of fusion...
