5-15 A soldering operation is done on electronic components on a workbench. The component is clamped in place on the bench by a foot-operated clamp for ease in doing the job. A small hood in the form of a flexible circular tube with a plain end is attached to the clamp to remove fumes generated in the soldering process; this is shown in Fig. 5-42. The electronic component is 15 by 24 by 5 cm high, with the 15 by 24 cm face resting on the bench. Estimate X and Q for this application, and determine the diameter of the tube for a velocity of 10 m/s in the tube and a control velocity of 0.25 m/s. Hood

Anatomy of a Syringe Plunger L Plunger tip Ваrel (Calibrated) Cannula (пеedie) Hub 1. A keloid scar is a thick, raised scar that is caused by an overly-aggressive wound-healing process in the body. People with darker skin are more susceptible to keloid scarring. They are treated by injecting steroids into the scar tissue, but because the tissue is so dense, high pressure is required. The average male can exert a force of 95.4 N on the plunger of a syringe. The average female can exert a force of 64.1 N. (Vo A, Doumit M, Rockwell G. The Biomechanics and Optimization of the Needle-Syringe System for Injecting Triamcinolone Acetonide into Keloids.

11-10. An ion-exchange resin has a capacity of 1600 eq/m³. The manufacturer recom- mends that the resin be regenerated when 75 percent of its capacity has been utilized. The regeneration cycle takes I h for draining, regeneration, and flushing the bed. The contact time in the bed(s) is to be 10 min when one bed is out of service and one bed is being regenerated. The plant is to reduce the hardness of a flow of 7000 m³/day from 250 to 100 mg/L as CaCO3. Determine the total volume of resin required and the number of beds to be used. What is the frequency of regeneration which would be required?
