5. Consider the situation of the previous problem. Assumethat the temperature of the water at the bottom of thelake remains constant at 4°C as the ice forms on thesurface (the heat required to maintain the temperatureof the bottom layer may come from the bed of the lake).The depth of the lake is 1.0 m. Show that the thicknessof the ice formed attains a steady state maximum value.Find this value. The thermal conductivity of water= 0:50 W m oc. Take other relevant data from theprevious problem.
