Anyone can help me with this question? 2 - Heat pump .The heat pump illustrated beside...
The heat pump illustrated beside uses 1.5 kW mechanical power (that's is 1500 J/s) and extracts 1.2 million calories per hour from the outside air. • A) How much heat is pumped into the house every day? • B) If this heat pump is made such that it is ideal and reversible, and you decide to heat your house with a gas furnace and use the heat pump as an heat engine to produce mechanical work, then what would be...
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...
2. A heat pump is operated to maintain a home at 25 °C when the outside temperature is only -5 °C. (a) If the house requires 50 kW heat, what is the power required for the heat pump? Assume the heat pump to be a Carnot heat pump (b) If an electric heater was used for this purpose instead, assuming an electric current of 5A, what would be the required resistance of the heater? (c) If electricity costs 10 cents...
Can someone help pls!!! Question 1 (3.5 marks) A heat engine is a mechanism that transfers energy from a warm to a cool region, converting some of that energy into mechanical work. The following equation describes the process analytically W n(1) TH' where: W is the work done by the heat engine is the coefficient of maximum efficiency Tc is the absolute temperature of the cool region TH is the absolute temperature of the warm region (a) Derive the linearised...
Hi, I have problem solving this problem, can anyone help? I have no idea.. Please help me solving the problem step by step with well explanation. Thanks in advance! 谢谢 My sister bought a home in east county and I drove out there to watch a movie with her. As I headed away from the coast, I noticed the temperature on my car’s outside thermometer kept rising. I recorded a few data points as (distance from coast in miles,temperature in...
