Hide AnswerTry Another The formula for piston displacement is P = cd2SN, where c is a constant, d is the cylinder bore, S is the stroke, and N is the number of cylinders. For c = 0.7854, d = 3.000, S = 4, and N = 6, find the piston displacement. (Use the rules for working with measurements to give your answer to the appropriate accuracy and/or precision. Note: The values for S and N are exact numbers. Ignore exact numbers when determining the appropriate accuracy and/or precision.)

Study the table to the right and then answer these questions by filling in the blank columns in the table.1. Convert the miles per gallon figures in the table tokilometers per liter (kpl).2. How many liters (and how many gallons) of gasolinewould each type of car use annually if it were driven19,300 kilometers (12,000 miles) per year?3. How many kilograms (and how many pounds) of carbon dioxide would be released into the atmosphereannually by each car, based on the fuel consumptioncalculated in question 2? Assume that the combustion of gasoline releases 2.3 kilograms of CO2 per liter(19 pounds per gallon).
Atmospheric pressure can be reported in several ways. At sea level the average atmospheric pressure is 15 lbs/sq in, or 101.3 kPa, or 760 mm Hg, or 1 atmosphere. Since all of these are equal, you can easily convert from one to the other. For example, if your tire pressure is 32.0 lbs/square inch, you can determine the kilopascals in the following manner: 32.0 lb/sq in X 101.3 kPa / 15 lbs/sq in = 216 kPa. Now, find the pressure in mm Hg of a container that has a pressure of 9.92 atm. mm Hg
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.
The most accurate method of fluid flow measurement is ___________ flow measurement. a. velocity b. mass c. density d. volume
The velocity of the fluid flowing in a pipe with a radius of 10 cm was measured at certain points and the following table values were obtained. r=the distance of the measurement points to the center of the pipe (m) v=measured speeds (m/s) Accordingly, calculate the velocity value for r = 0.07 m by using 3rd order interpolation with the help of appropriate points that make the error minimum. In calculations, take 4 digits after the comma.
The correct definition of Dimensional Analysis is: A procedure to find the yield point of a material when no definitive yield point can be determined graphically. A procedure to calculate the Elastic Modulus. A procedure to verify the size of a mass of material. A methodical process of converting from one set of units to another set of units. Match the following statements with the term that best describes each statement. (Enter Number ONLY) 1) Hooke’s Law 2) Creep 3) Impact Strength 4) Proportional Limit 5) Fatigue 6) Elastic The tendency of a solid material to move slowly or deform permanently under the influence of mechanical stresses below the yield strength of the material. The behavior of materials that deform when loaded but return to their original shape after the load is removed. The linear relationship between stress and strain in the elastic region below the proportional limit. The phenomenon where cracks propagate under loads…
Suppose you're converting a bill of materials for machining feedstock from the British gravitational (U.S. system) of units to International System (SI) units. Your goal is to have all of the material quantities in kilograms. Your bill of materials lists values for required weights of brass rod in pounds. To convert to these values to kilograms you first you divide by gravitational acceleration in feet per second squared to get a mass in slugs, then convert slugs to kilograms using standard conversion factors. Group of answer choices True False
You step on a digital scale, which tells you that your mass is 84.6 kg. From this, you assume that the absolute error is 0.1 kg. What is the relative error of this measurement?
