Question
An egg with mean diameter of 4 cm and initially at 25 degree Celsius is placed in an open boiling water container for 4 minutes and found to be boiled at a particular level. For how long should a similar egg boil at the same level, when refrigerator temperature is 5 degree Celsius? Use lumped parameter theory and assume following properties of egg
k = 12 W/m K
h = 125 W/m² K
c = 2 k J/kg K
p = 1250 kg/m³
k = 12 W/m K
h = 125 W/m² K
c = 2 k J/kg K
p = 1250 kg/m³
