Question: A man is found dead in a room at 16C. The surface temperature on his waist is measured to be 23C and the heat transfer

A man is found dead in a room at 16°C. The surface temperature on his waist is measured to be 23°C and the heat transfer coefficient is estimated to be 9 W/m2 · °C. Modeling the body as 28-cm diameter, 1.80-m-long cylinder, estimate how long it has been since he died. Take the properties of the body to be k = 0.62 W/m · °C and α = 0.15 × 10-6 m2/s, and assume the initial temperature of the body to be 36°C.
