I want two questions similar to the attached question with their solutions

Example: A viscous solution containing particles with a density P=1461kg/m3 is to be clarified by a centrifugal separator. The solution density is 801kg/m3 and its viscosity is 100cp (0.1 Pa.s). The centrifuge has a bowl with r2=0.02225m and r1=0.00716m, and height b is 0.197m. Calculate the critical particle diameter in the exit liquid stream if N=23000rev/min and the flow rate q=0.002832m3/h
