www.math.ucdavis.edurepresent the heat and wave equations in the polar coordinate system. For the heat equation, the solution u(x,y t)˘ r µ satisfies ut ˘k(uxx ¯uyy)˘k µ urr ¯ 1 r ur ¯ 1 r2 uµµ ¶, k ¨0: diffusivity, whereas for the wave equation, we have utt ˘c 2(u xx ¯uyy)˘c 2 µ urr ¯ 1 r ur ¯ 1 r2 uµµ ¶ c ¨0: wave velocity. 3

www2.et.byu.eduThe Froude number is also the ratio of the flow speed to wave speed, Fr = V /co. Discussion The Froude number is the most important parameter in open-channel flow. 13-11 Solution A single wave is initiated in a sea by a strong jolt during an earthquake. The speed of the resulting wave is to be determined. Assumptions The depth of water is constant,
