Name a common device or appliance that you are familiar with that uses a heat pump. Describe its operation in terms of a Carnot engine and estimate its Carnot efficiency. Remember to show your work and explain how you estimated the efficiency. If you could please answer with a WRITTEN response, not just equations and math. I am trying to understand it conceptually rather than mathematically.

A Carnot heat engine uses a hot reservoir consisting of a large amount of boiling water and a cold reservoir consisting of a large tub of ice and water. In 5 minutes of operation of the engine, the heat rejected by the engine melts a mass of ice equal to 5.45×10−2 kg . Throughout this problem use Lf=3.34×105J/kg for the heat of fusion for water. A.) During this time, how much work W is performed by the engine?

A Carnot heat engine uses a hot reservoir consisting of a large amount of boiling water and a cold reservoir consisting of a large tub of ice and water. In 5 minutes of operation of the engine, the heat rejected by the engine melts a mass of ice equal to 4.30×10−2 kg . Throughout this problem use Lf=3.34×105J/kg for the heat of fusion for water. During this time, how much work W is performed by the engine?

earning Goal: To understand that a heat engine run backward is a heat pump that can be used as a refrigerator. By now you should be familiar with heat engines--devices, theoretical or actual, designed to convert heat into work. You should understand the following: Heat engines must be cyclical; that is, they must return to their original state some time after having absorbed some heat and done some work). Heat engines cannot convert heat into work without generating some waste...

1. Heat engines A heat engine is a device that does work by exchanging thermal energy with its environment. All heat engines operate in cycles during which a system, also known as the working substance, passes through a series of thermodynamic processes returning repeatedly to each state. A. Device 1, shown at right, represents a heat engine operating between 900 K reservoirs at 900 K and 400 K. (The system interacting with the reservoirs...
