Sorry for the delay since my last question. I have been traveling for work. My next question is to read the attached Unit V Study Guide, then review the calculations demonstrated and explained regarding face velocity calculations and filter velocity calculations for our scenario. Make your Unit V work your fourth level 1 heading titled "Operational Face and Filter Velocities." Describe and demonstrate (illustrate) the calculations for the following for this section of your project: (a) calculate the face velocity and (b) filter velocity of the spray booth in a minimum one-page, double-spaced document. As always please cite work as appropriate and reference all citations. If possible, please add an additional reference.
