A soda straw with an inside diameter of 0.125 in. is inserted into a pan of water at \(60^{\circ} \mathrm{F}\). The water in the straw rises to a height of \(0.150 \mathrm{in}\). above the water surface in the pan. Determine the value of \(\theta\), the contact angle of the water with the straw (see Fig. 1.10).
