A square disc is placed in a moving liquid, the drag force on the disc is 6.3 lbs when the liquid has a velocity of 3.4 ft/s. If the liquid has a density of 78.3 lb/ft³
and the drag coefficient is 0.41, what is the size of the square?

The 8 × 32-in³
cylinders in a positive displacement meter assembly are rotating at a rate of 570 revolutions an hour. What is the average flow rate per min?
