7.10 Using Plank's equation, determine the freezing time for apotato sphere with a moisture content of 88%. The potatowill be frozen in a blast freezer where air is availableat -40°C and the convective heat transfer coefficient is40 W/(m² °C). The thermal conductivity of frozen potato isestimated to be 1.3 W/(m °C) and its density is 950 kg/m'The initial freezing temperature of potato is -2°C. Thediameter of the potato sphere is 2 cm.IS

Freezing time (tf) can be calculated as, Here,ρ= 950 kg/m3 denotes the density, mf= 0.88 denotes…
