Fluid lab 1 Quiz
I have all the materials to solve the Fluid Lab Quiz 1.
Quiz 1:
Lab Safety/Requirements/Ethics
1. What does MSDS stand for and where are the MSDS sheets located in the room? (1)
2. Do we work with any hazardous materials (cryogens, acids, ladders, etc.) in the lab? What two materials do we work with primarily? (2)
3. Indicate which section of the lab report each of the following requirements belongs to: (4)
E.g. List of all sections with associated page numbers: Table of Contents___________________
Equations used for analysis and Sample Calculations: __________________________
Brief summary of what was found and how it was done: ________________________
Tables, charts, and graphs showing final processed or calculated data: _____________
Labeled schematic of experimental setup: ____________________________________
4. When including material in your report from external sources, is it permissible to not cite where the information came from as long as you are only paraphrasing and not using direct quotes/values? (1)
Error Calculations
5. What is the name of the calculus-based error analysis that we use? (1)
6. The following is the General Thrust Equation for a small fuel/air ratio F-16 jet engine with an ideally expanded exit area (nozzle area designed to match exit pressure with the atmosphere). This jet engine can produce a thrust of over 125,000N (with an afterburner, also not relevant to the problem before you ask me, just a cool fact for accurate numbers). For the provided values below, complete an error calculation for dT: (8)
(no error)
Density
7. Provide a basic definition of Density, both in
words
and in
equation form
. (2)
8. Why is it interesting that all densities calculated in Lab 1 were less than 998kg/m^3? (2)
Specific Gravity
9. Provide a basic definition of Specific Gravity (that we measured, not ), in
words
and in
equation form
. (2)
10. What is the name of the glassware/instrument used to measure Specific Gravity? (2)
11. What is the difference between and , and what makes valuable? (2)
Dynamic Viscosity
12. What was the name of the apparatus that we used to obtain the value of Viscosity in the lab? (1)
13. What are two experimental/mathematical assumptions that we have made in this experiment that may have adverse effects on our calculated results? (2)
Extra Credit:
Pretend we are re-doing the viscosity lab, however during a hurricane the air conditioning units in the lab broke and now we are operating at 85 degrees F instead of 75 degrees F. What should happen to our measurement of viscosity? (2)
