[SOLVED] help setting up a CHEM E problem 1. The problem statement, all variables and given/known data Three fillers used in packaging a pharmaceutical emulsion (ro = 1050kg/m^3) are fed from a single product line. One filler has a capacity of 2700kg/h, the second operates at 4600 kg/h and the third at 6800 kg/h. The emulsion is susceptible to damage at velocities greater that 1.2m/s, due to shear at the pipe wall. What size (ie minimum inside diameter) in cm should be used to feed the fillers through a single line? 2. Relevant equations ro = mass flow rate / volumetric flow rate and do i use the v1A2=v2A2 where v = velocity and A = area to determine the size of thepipe. b]3. The attempt at a solution[/b] ok so i add the mass flow rates and get 14,100 kg/h then i thought i should make this kg/s so i got 235 kg/s then into volumetric flow 235/1050 = 0.224 m^3/s now i draw a blank why cant i remember how to make m^3 into m do i cube root or ?? and then do i use the v1a1=v2a2 do set up my pipe??
