A 5kW heater is in the lab, but the lab losses heat to its outside surroundings. The heat transfer rate between the lab and the outside is given by the equation dQ/dt = UA(T -To), where Ti and To are the inside and outside temperatures respectively, U is the overall heat transfer coefficient with a value of 5W/°C%2 and A is the exposed surface area of the lab with a value of 30 m2. Describe the thermodynamic operation and properties of this system and the names associated with this type of system. If the outside temperature is 10°C, then using the first law explain what the indoor temperature of the lab will become.

Transcribed Image Text:A 5kW heater is in the lab, but the lab losses heat to its outside
surroundings. The heat transfer rate between the lab and the
outside is given by the equation dQ/dt = UA(T-T.), where Ti and
To are the inside and outside temperatures respectively, U is the
overall heat transfer coefficient with a value of 5W/°CM2 and A is
the exposed surface area of the lab with a value of 30 m2.
Describe the thermodynamic operation and properties of this
system and the names associated with this type of system. If the
outside temperature is 10°C, then using the first law explain what
the indoor temperature of the lab will become.
