Chapter 3, Problem 3.47P

In the movie, Willy Wonka and the Chocolate Factory, Augustus Gloop leans over the chocolate river to get a drink and falls in. He is sucked through the pipe leading to the fudge room where he is saved by the Oompa Loompa workers. Unfortunately, real-life accidents do not always have such happy endings, even when they involve chocolate. In a tragic 2009 accident, a worker suffered fatal injuries after falling into a cylindrical mixing vat that had an 8-ft diameter and was 8 ft tall. At the time of the accident, the vat was full of molten chocolate.

1. What was the total weight (lbf) of chocolate in the vat? The specific gravity of chocolate is approximately 1.24.
2. Determine the pressure (psig) at the bottom of the tank.
3. Speculate on w hether a person would float or sink in the vat and list two possible causes of the worker’s death.
