How do you calculate Carnot police?
At an average temperature of −19°C, the COP for a Carnot refrigerator would be (273 − 19)/(25 − (-19)) = 5.772. Since the COP = Qc/W, the minimum work can be calculated as W = Qc/COP = 1,604/5.772 = 184.3 kJ.
How does the four 4 laws of thermodynamics apply its rules to a refrigerator when a hot soup is placed inside it?
How does the four (4) Laws of Thermodynamics apply its rules to a refrigerator when a hot soup is placed inside it? The application of the laws of thermodynamics to a refrigerator when a hot soup is placed inside it is the same as to a refrigerator without a hot soup.
What is the COP formula?
COP (Coefficient of Performance) COP is defined as the relationship between the power (kW) that is drawn out of the heat pump as cooling or heat, and the power (kW) that is supplied to the compressor. For example: A given heat pump used for air cooling has a COP = 2.
How do I calculate heat pump capacity?
Here’s the 1 rule of thumb:
- 30 BTU of heating output per 1 sq ft of living space.
- Heat Pump Size (2,500 sq ft) = 2,500 sq ft * 30 BTU per sq ft = 75,000 BTU.
- Mini-Split Heat Pump Size (1,500 sq ft) = 1,500 sq ft * 30 BTU per sq ft = 45,000 BTU.
How do I find the COP of the heat engine?
For such a device we define the coefficient of performance COP as the ratio of the amount of heat removed at the lower temperature to the work put into the system (i.e. the engine). COP = Qlow/(-W) = Qlow/(Qhigh – Qlow).
What is the formula of COP?
What are the standard physics equations for MCAT?
Gold Standard MCAT Physics Equations – Units to Memorize. Both work and energy are measured in joules where 1 joule (J) = 1 N × 1 m . {Imperial units: the foot-pound , CGS units: the dyne-centimeter or erg }. The SI unit for power is the watt (W) which equals one joule per second (J/s) = volts × amperes.
