To measure the water depth in a large open tank with opaque walls, an open vertical glass tube is attached to the side of the tank. the height of the water column in the tube is then used as a measure of the depth of water in the tank (a) for a true water depth in the tank of 3 ft, determine the percent error due to capillarity for 0.25 increments of diameter, d, from 0.25 in to 1.0 in. (b) if you want the error to be less than 1%, what is the smallest tube diameter allowed?
