Question

lity that produces soluble coffee, solid spherical coffee beans from 3 different dryers having 40 μη, 400 μ m ạnd 4000 um particle size fall from the air at 422 K. The density of the particles is 030 kg/m. Under these conditions for air p-0.838 kg/m1 and u-2.37x10 Pa.s. Write a program that In a facil 1 calculates the terminal speed of the coffee particles using the MATLAB program. /3 Criteria equation (K): KSPPp-p Equation table to be used in calculation of terminal speed according to criterion equation Region K<2.6 Stokes' Law Trial&Error Intermediate Region 2.6<K <68.9 Newtons' Law 69.9<K2360 Give your results in a file with a .txt extension, such as the table given below Criteria Value Terminal Velocity ut (m/s) Particle Diameter (micron)

Answer 1

didnt gave the exact information about drag.so i assumed that cd=24/Re where Re is reynolds number .and simplified the equation and inserted in matlab code
