Question 21
XE-GNAT2 marksNeeds review
Green pea (average diameter 0.8 cm) is frozen in a blast freezer operating at -40°C and with a surface heat transfer coefficient of 30 W m^ K^. The thermal conductivity of pea is 2.5 W m^ K^, and latent heat of crystallization is 2.74 x 10^2 kJ kg^. If the freezing point of pea is -1°C and the density is 1160 kg m^, the freezing time in minutes will be ______.(up to two decimal points)
