25. A horizontal glass tube 10 cm long is connected at one end to the contents of a wide container through its wall. The container is filled with water (density 1.00 g/cm3; viscosity 1.00 mPa*s) to a height of 25 cm above the tube. It takes 60 seconds to draw 200 cm3 of water through the tube. What is the diameter of the tube? Assume that the water level in the container does not change when this volume flows out.
