Chapter 7, Problem 7.17CP
For the following computer problems, any appropriate software may be used. Input prompts should fully explain what is required of the user (the program should be user-friendly). The resulting output should be well labeled and self-explanatory. For spreadsheet problems, any appropriate software may be used.
7.17 Use a spreasheet program to solve for the centroid location of built-up areas such as shown in Problem 7.12 
and 7.28. 
The user should be able to input the appropriate geometric properties for any shapes of the types shown, and the program should then determine the centroid location and display the result. Vary a single shape or dimension and observe how the location of the centroid is affected.

Problem Solving
Instructions; Analyze and solve the following problems. Enclose your final an-
swer in a box.
1. A block of steel (sg=7.85) will float at a mercury-water interface. What will be the ra-
tio of x and y for this condition.
2. An iceberg in the ocean floats with one seventh of its volume above the surface. What
is its specific gravity relative to the ocean water? What portion of its volume would
be above the surface if ice were floating in pure water? sg=10.10KN/m^3
3. A rectangular 9m wide, 15m long, and 3.6m high has a draft in sea water of 2.4m. Its
center of gravity 2.5m above the bottom of the scow. Determine the initial metacen-
tric height and the righting moment or overturning moment when the scow tilts until
one side is just at the point of submergence.

Your division is tasked with providing computer-based modeling and design solutions using computational fluid dynamics through ANSYS software. Your primary responsibilities involve the analysis of horizontal channel dynamics to meet specific criteria. Under the guidance of your immediate supervisor, you have been assigned unique responsibilities within an ongoing project. As a member of the research team, your role includes constructing an appropriate model and executing a sequence of simulation iterations to explore and enhance channel performance. Figure 1 provides a visualization of the horizontal channel under consideration. Consider 2D, incompressible, steady flow in a horizontal channel at a Reynolds number of 150. The schematic below illustrates the channel flow, not drawn to scale. For simplicity, neglect gravity. The…arrow_forwardSOLVE STEP BY STEP, DONT USE AIarrow_forward
