A person is found dead at 5 PM in a room whose temperature is 20 °C. The
temperature of the body is measured to be 25 °C when found, and the heat transfer
coefficient is estimated to be h 8 W/m2 °C. Modeling the body as a 30-cm-diameter,
1.70-m-long cylinder, estimate the time of death of that person. The body can be
modeled as a 30 cm diameter, 1.70-m-long cylinder. The thermal properties and body
temperature of 37 °C.
let The average human body is 72 percent water by mass, and thus
we can assume the body to have the properties of water at the average temperature
of (37 + 25)/2 = 31 °C; k = 0.617 W/m · °C, p= 996 kg/m³, and Cp=4178 J/kg · °C
