Swim Bladder Many ray-finned fish adjust their buoyancy by changing the volume of gas in a swim bladder located just below their spine.
Calculate the change in the buoyant force on a fish if its volume increases by 14 cm3, assuming it swims in seawater.
Homework Answers
Buoyant force, B = pVg
B = 1030 x 9.8 x 14 x 10^-6
B = 0.14 N

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
