1.B.) - A person is in a room with an air temperature of 20°C. The exposed surface area and the skin temperature of the person are 1.7 m and 32°C, respectively. The emissivity of the skin and the clothes are 0.9, and the convection heat transfer coefficient between the person and the air in the room is 5 W/m2-K. Determine the total rate of heat transfer from the person if: (a) The inner surfaces of the room are at the same temperature as the air; (b) The inner surfaces of the room are at a temperature of 5°C during the winter time. Stefan-Boltzmann constant: o = 5.76x10¯8 W/m²·K*

**Title: Thermodynamics Problem - Heat Transfer from a Person in a Room** **Problem Statement:** A person is in a room with an air temperature of 20°C. The exposed surface area and the skin temperature of the person are 1.7 m² and 32°C, respectively. The emissivity of the skin and the clothes is 0.9, and the convection heat transfer coefficient between the person and the air in the room is 5 W/m²·K. Determine the total rate of heat transfer from the person if: (a) The inner surfaces of the room are at the same temperature as the air. (b) The inner surfaces of the room are at a temperature of 5°C during the winter time. **Constant:** Stefan-Boltzmann constant: σ = 5.76 x 10^(-8) W/m²·K⁴ **Notes:** This problem involves determining heat transfer via both convection and radiation. The student's task is to evaluate the conditions described in parts (a) and (b) and compute the total rate of heat transfer accordingly.
