Your newly purchased house where you are aiming for an indoor temperature of 18.0°C is well insulated apart from a 5.0 cm thick 12m² wooden wall facing the garage. Typically, the garage maintains a temperature of at least 9.0°C even in winter. What power do you lose because of the wall? One winter evening, the garage door gets stuck in the upright position and you want to know what the indoor temperature will be when the coldest night is -15.0 ° C in the garage. You can heat the room with a 400 W power element.

Expert Solution

The rate of heat energy transfer through the conduction process is a function of thermal conductivity of the material considered, area of the surface considered, the temperature of the hot region as well as cold region, and the thickness of the material considered.

In the given problem by fourirer law of conduction first we need to find the thermal conductivity of wall materials to find the required heat loss.

Q1. You want to keep the indoor temperature of an office at 25oC. The outdoor temperature is 5oC. The heat transfer through the building’s exterior is 3 x 106 kJ. To achieve the desired indoor temperature, you are exploring three heat pumps operating between the office interior and: (i) the ground at 12oC; (ii) a pond at 10oC; and (iii) the air outside at 5oC. For each case, what is the minimum theoretical net work input (in kJ) any heat...

A dead body was found within a closed room of a house where the temperature was a constant 70° F. At the time of discovery the core temperature of the body was determined to be 80° F. One hour later a second measurement showed that the core temperature of the body was 75° F. Assume that the time of death corresponds to t = 0 and that the core temperature at that time was 98.6° F. Determine how many hours...

You just purchased the lockbox below to store a spare set of keys for your house. It allows you to set a passcode using digits from 0 to 9: How it works: -Each digit is either ON or OFF, so pushing the same button twice removes it from the combination (as opposed to adding it a second time to the code). E.g. pressing 2, 7, 4 or pressing 2, 7, 3, 4, 3 would produce the same code: 274 -It...
