A small metal cube with a thermal mass mc and an initial temperature 0 is dropped into a container of water that is actively maintained at a constant temperature 0w. The cube quickly comes to rest on the bottom surface of the container. The bottom surface is maintained at a constant temperature 0 (note that this is different from 0w). The thermal resistance between the cube and the water is Rcw while the thermal resistance between the bottom surface of the container and the cube is RCB. The temperature of the cube is denoted by 0c. a) Draw the system schematic indicating the assumed directions of the heat transfer rates. Label all the nodes and system parameters. b) Derive the governing equation for the temperature of the cube, 0c. c) Where does to appear in the system schematic and how does it affect the governing equations? d) Calculate the steady-state temperature of the cube, css, assuming the following system parameters: 0o = 21°C, 0B = 6°C, 0w = 0°C, Rcw = 2°C/W, and RCB = 4°C/W

A small building has a heater inside it running with its door left open. The heater is the only device in the building. When the heater runs, it consumes 250 W. The building is 3m X 3m X 2.5m. The temperature outside is 25 degrees celsius, and the the wind is blowing at 10km per hour. Estimate the temperature inside the building if the walls and ceiling are made of 13 mm thick plywood and 13 mm thick drywall with 100 mm of air inbetween. The floor is perfectly insulated and there aren't any cracks in the walls ceiling or door frame. Make any other reasonable assumptions as needed
