Question

Please look up some data and assumptions on google if needed.... just indicate the assumptions in the answer

4. In this problem we will consider various aspects of how a shark maintains its depth in the water. Sharks have a problem in that, lacking swim bladders, they tend to be negatively buoyant. They have to keep swimming to generate lift to maintain their depth in the water. We will also in the process consider the process of "induced drag" (sometimes called "lift-induced drag"), which is drag caused by the generation of lift. (This question is worth twice as much as the previous questions.) A A bull shark has a lean tissue density of 1076 kg/m3, and a liver tissue density of 964 kg/m3. (The fatty liver is the only buoyant tissue in the shark.) If the liver is 14% of the volume of the shark, and the shark's total volume is 0.0138 m then estimate the net lift force that the shark must generate when travelling at constant depth, for a shark in sea water (p = 1.024). Then calculate it for the case of the shark being in fresh water (ρ= 1.000)
