Forces exceeding those of earth's gravitational acceleration are important for astronauts, fighter pilots, and centrifugation to separate cells from a broth. estimate quantitatively the hydrostatic pressure (in units of atm) at the bottom of an open centrifuge tube that is 3 cm long, filled with water to a depth of 2 cm when held upright, and is spun in a laboratory centrifuge at 5000 rpm. assume the tube spins with its opening to the center of rotation, and the long axis of the tube at 90 degrees to the rotor axis of the centrifuge. the top of the centrifuge tube is 9 cm from the center of rotation. use the problem solving checklist. you may assume a single value of acceleration, justify your choice. look up how a laboratory centrifuge works, what the rotor is, and any other unknown items as needed.
