Webprevious index next. Stokes’ Law and the Coffee Filters. Michael Fowler. A Problem. We found that Stokes’ Law, which we derived in the form . F drag = C a η v. from purely dimensional considerations (Stokes did the hard part of proving that C = 6 π ) correctly predicted that for two small steel balls, one having a radius exactly twice the other, the … WebWe determined the drag coefficient of our coffee filter to be 0.93. Since thedrag coefficient of a long cylinder is about 0.82 and of a short cylinder is about 1.15, we can assume that …

Webcoffee filter experiment. If we drop a single coffee filter, it reaches a terminal velocity of about 0.8 meters per sec after falling less than a meter. If we drop a stack of four close … WebOct 22, 2013 · First, find the average terminal velocity for each number of filters. Drop a filter from a high enough height, that it will reach terminal velocity very early on (like 2m). Record the time that it takes the filter to fall. Repeat this for two filters and three filters. For each number of filters, divide the height it fell by the time it took in ... meatgq橡木炙烤牛排館

Stokes’ Law and the Coffee Filters - University of Virginia

WebFirst, measure the mass of each coffee filter in kilograms and record this in data table 2. If your scale measures in grams, divide that number by 1,000 to get kilograms. 2. Next, get … Web15) According to the data and the force of drag equation, force is directly proportional to velocity, the relationship between them being a squared one. 16) The Stokes equation for the drag force works perfectly well, considering that the coffee filters are traveling at low velocities. The Newtonian equation is not necessary with an n value of 2. Webone shown in the figure above, and dropping the stack from rest. The students change the number of filters in the stack to vary the mass m while keeping the shape of the stack the same. As a stack of coffee filters falls, there is an air resistance (drag) force acting on the filters. (a) The students suspect that the drag force F meath age friendly strategy
