Sing a motion sensor, describe how a coffee filter moves through the air: by changing the weight of the filter (adding layers), find out which model of drag it abides by. how do you come to this conclusion? either: fd=-bv or fd=-av2 model the velocity of the filter, starting with newton’s laws, based on the type of drag that was affecting it. export your data for velocity and time to sheets and model it using the trendline function. based on what your data gives you, does it match your velocity model?

6–55 refrigerant-134a enters the condenser of a residential heat pump at 800 kpa and 358c at a rate of 0.018 kg/s and leaves at 800 kpa as a saturated liquid. if the compressor consumes 1.2 kw of power, determine (a) the cop of the heat pump and (b) the rate of heat absorption from the outside air.
