A smooth steel sphere of specific gravity (SG) 7.82 and diameter25.4mmis dropped into a large tank of oil(r= 820kg/m3,μ=0.9Pa.s). Calculate the terminal velocity of the sphere noting that drag coefficient is a function of Reynolds number as shown in Figure 1

.Hint you will need to perform an iterative calculation.[Answer 1.2m/s without buoyancy or 1.1 m/s with buoyancy

Expert Solution

Ans. Note : Dear student I have solved the question without considering the drag coefficient value as per questions and hint available the value of reynolds no is not present here.Fig 1 is not attached here to perform iterative calculations.

Please provide Fig 1 for complete solution. You may see the current solution how to approach the problem to get terminal velocity.

The Clap Chemical Company needs a large insulated stainless steel tank to expand its plant. A recently closed brewery has offered to sell their tank for $15,000 delivered. The price is so low that Clap believes it can sell the tank at any future time and recover its $15,000 investment. Installing the tank will cost $9000 and removing it will cost $5000. The outside of the tank is covered with heavy insulation that requires considerable maintenance. This will cost $3500...
