2.15b. Dissolution of a solid sphere into a flowing liquid stream

2.15b. Dissolution of a solid sphere into a flowing liquid stream The crystal of Problem 1.26 is a sphere 2cm in diameter. It is falling at terminal velocity under the influence of gravity into a big tank of water at 288K. The density of the crystal is 1464kg/m3 (Perry and Chilton, 1973). (a) Estimate the crystal's terminal velocity. Answer: 0.56m/s (b) Estimate the rate at which the crystal dissolves and compare it to the answer obtained in Problem 1.25
