The chart below lists six stars. Research the visual luminosity, distance from Earth, and surface temperature of each star. Make sure to research credible sites, such as nasa. gov, to complete your chart. Distances should be given in light years and temperatures given in Kelvin. Visual luminosity (L) is how bright something is in human eyesight. As you conduct your research, look for the visual luminosity of each star relative to the Sun. (Therefore, the visual luminosity of the Sun is 1). If your sources give a fraction for visual luminosity, convert the fraction into a decimal number. Use your research to complete the chart.

Acommercial refrigerator with refrigerant-134a as the working fluid is used to keep the refrigerated space at -35°c by rejecting waste heat to cooling water that enters the condenser at 18°c at a rate of 0.25 kg/s and leaves at 26°c. the refrigerant enters the condenser at 1.2 mpa and 50°c. if the compressor consumes 3.3 kw of power, determine (a) the mass flow rate of the refrigerant, (b) the refrigeration load, (c) the cop, and (d) the minimum power input to the compressor for the same refrigeration load.
