Textbook Question
Chapter 1, Problem 1.37P
A common scenario: An engineer has two pencil- style pressure gauges in her garage for setting tire pressures. She notices that the two gauges disagree by about 14 kPa (2 psi) on the same tire. How does she choose the most accurate gauge to set car tire
pressures? Discuss possible strategies she might use to arrive at her best option.

Bourdon-type pressure gauges are used in thousands of applications. A deadweight tester is a device that is used to calibrate pressure gauges. Investigate the operation of a deadweight pressure tester. Write a brief report to discuss your findings.
List three sources of error that would account for the differences between your values and the accepted value. Some of your focus should be on considering that heat transfer should only have taken place between the water and the unknown substance in the calorimeter.
Construct a plot showing the sequence of events on an oil viscosity vs. pressure for the given reservoir below. A reservoir was discovered in an undersaturated condition (call this state, point A). Gas was injected to maintain pressure (point B), and eventually formed a secondary gas cap (point C). Water injection was employed to increase the reservoir pressure (above discovery pressure) until an undersaturated condition existed again (point D). Finally, all injection ceased and the reservoir was blown down to abandonment pressure (point E).

This is best done when the tires are cold meaning; the car has not been driven for at least 2 hours. Since you leave for work before the sun comes up you decide to inflate your tires to the recommended pressure right after you get home from work in the afternoon when the tires are still warm. What would you find if you rechecked your tire pressure after the tires have cooled down? A.Tire pressure has decreased because there is a decrease in kinetic energy of themolecules resulting in more collisions with the inside walls of the tire thusincreasing the pressure inside the tire. B.Tire pressure has increased because there is a decrease in kinetic energy of the molecules resulting in fewer collisions with the inside walls of the tire thus decreasing the pressure inside the tire.

- 1.The thickness of a gage block is measured five times using an instrument that has a resolution of 0.001 cm. The following measurements are obtained (in cm): 1.100, 1.110, 1.090, 1.095, and 1.105. The true gauge block thickness is known to be 1.050 cm. Use this information to answer the following questions: a. What errors or sources of measurement error can be identified in the example? (Hint: there are three). Identify each one as a random or systematic uncertainty. b. Estimate the magnitudes of each of these uncertainties. Wherever possible, estimate random uncertainties at a 95% probability/confidence level. c. Based on the uncertainties determined in part b, estimate the overall uncertainty of a measurement obtained by this instrument.arrow_forwardDescribe the extent to which your data indicate that mechanical energy is conserved.
