The first homework covered the building blocks of this fluid mechanics course such as, computations using the Pressure and Force formulas. Applying the Bulk Modulus formula to compress mercury by 1% \u2026 I learned it would take 35,594 psi! Compare that to the 14.7psi in our atmosphere. Specific weight and specific gravity were new concepts, and both were a little less challenging after working through a couple problems. Viscosity was the last subject covered and, besides manipulating the formula, I gained a visual of how viscosity is inversely proportional to temperature in liquids, but the opposite is true for gases.<\/p>\n\n\n\n
The second homework tested my understanding of the relation between absolute, gage and atmospheric pressure, why absolute pressure cannot be negative and the need of a reference when speaking about gage pressure.<\/p>\n\n\n\n
The next homework covered the Pressure-Elevation relationship with formula P= gamma (h). Based on the levels of fluids in a manometer I calculated pressure at a specific point. Conversions between inches of mercury and pressure units seemed simple but I was fortunate to catch my mistake by looking at my answer (problem 3.90) and understanding the answer was not reasonable. I also calculated forces due to gas pressure, forces on a horizontal surface under the pressure of a liquid. I struggled a lot with Forces on Rectangular Walls (problem 4.17) but realized I was not using the correct number for the specific weight of water and that helped me in later problems like Forces on Submerged Plane Areas and on Curved Forces.<\/p>\n\n\n\n
Lastly the problems of Buoyancy and stability of objects in a fluid was very useful in understanding the relationship of the center of buoyancy above the center of gravity for floating objects and how they relate to the Metacentric height.<\/p>\n\n\n\n
The class work was very challenging but I learned a lot from the assignments and I can relate a lot to life experiences like swimming, working on cooling systems and living on a ship.<\/p>\n\n\n\n
