Question

I have done parts 1-3 and provided the answers I need parts 4-6 please and show the work I can't get past part 4 

003 (part 1 of 6) Answer = 8.12 For a plant design flow of 84 MGD and 9 parallel process trains, what is the required volume of the in-line blender (flash mixing) chamber of each treatment train with a mean hydraulic residence time of TRM = 0.5 s? In these calculations, consider the possibil- ity that one process train could fail, so calcu- late the design flowrate of each process train by dividing the plant flow rate by (n-1) so that the remaining operational process trains have sufficient capacity for the entire plant flow. Answer in units of ft³. 3.12 → Den 004 (part 2 of 6) Answer = 1.72 What is the diameter (ft) of a cylindrical in-line blender chamber with a length-to- diameter (L/D) ratio of 2. Answer in units of ft. 4 1.72 005 (part 3 of 6) Answer 3.46 What is the length, L (ft), of the cylindrical in-line blender chamber? Answer in units of ft. 3.44 → дини 006 (part 4 of 6) Need Answer Calculate the mixing power (hp) required for the in-line blender chamber for a mixing in- tensity of 4300 s -1 at 40 °F (3.2 x 10-5 lbf-s ft2 (1 hp = 550 ft-lb/s) Answer in units of hp. yd no007 (part 5 of 6) Need Answer Assuming mixing efficiency of 75 percent, calculate the motor horsepower required. (Round up your answer to the nearest stan- dard motor horsepower rating which are 1, 1.5, 2, 3, 5, 7.5, 10, 15, 20, 25, 30, 40, 50, 60, 75 hp.) at Answer in units of hp. W noi 008 (part 6 of 6) Need Answer Calculate the actual mixing intensity deliv- ered by the rounded-up motor size. (Note: 1 hp = 550 ft-lb/s) Answer in units of s-¹.
