- A group of students wish to determine the density of a cylinder to beused in a design project. They plan to determine the density from measurementsof the cylinder's mass, length, and diameter, which have instrumentresolutions of 0.1 lbm, 0.05 in., and 0.0005 in., respectively.The balance used to measure the weight has an instrument uncertainty(accuracy) of 1 %. The rulers used to measure the length and diameterpresent negligible instrument uncertainties. Nominal values of the mass,length, and diameter are 4.5 lbm, 6.00 in., and 4.0000 in., respectively.(a) Estimate the zero-order uncertainty in the determination of the density.(b) Which measurement contributes the most to this uncertainty?(c) Estimate the design-stage uncertainty in the determination of thedensity.arrow_forward14.11. As we explained in Chapter 7, the air resistance to motion of a vehicle is something important that engineers investigate. As you may also know, the drag force acting on a car is determined experimentally by placing the car in a wind tunnel. The air speed inside the tunnel is changed, and the drag force acting on the car is measured. For a given car, the experimental data is generally represented by a single coefficient that is called drag coefficient. It is defined by the following relationship: Fa Cả where Ca = drag coefficient (unitless) Fa = measured drag force (N or 1b) p= air density (kg/m³ or slugs/ft') V = air speed inside the wind tunnel (m/s or ft/s) A = frontal area of the car (m? or ft') The frontal area A represents the frontal projection of the car's area and could be approximated simply by multiplying 0.85 times the width and the height of a rectangle that outlines the front of a car. This is the area that you see when you view the car from a direction normal to…arrow_forwardYou pass by a building site and see a crane that lifts loads to upper floors of a building under construction. You wonder about the magnitude of the forces that support the beam of the crane. You snap a photograph of the crane with your smartphone. Back at home, you make a drawing of the crane from your photo. Your drawing is shown in the following figure. m M B *CM You estimate the lengths d and I by measuring the distance between floors on a point of the building the same distance from your smartphone as the crane and using that distance as a scale for the drawing. This tells you that d 1.00 m and t = 6.00 m. You have drawn the force vector for the gravitational force on the beam of the crane, but then you realize you don't know where the center of mass of the beam is located. You run back to the construction office and explain your interest. You ask the construction foreman about the crane, and he tells you that the crane itself has a mass of m₁ = 2,875 kg and the load it was…arrow_forward
- In this problem you are asked to investigate how much water a leaky faucet wastes in one week, one month, and one year. Perform an experiment by placing a container under a leaky faucet and actually measure the amount of water accumulated in an hour (you can simulate a leaky faucet by just partially closing the faucet). You are to design the experiment. Think about the parameters that you need to measure. Express and project your findings in gallons/day, gallons/week, gallons/month, and gallons/year. At this rate, how much water is wasted by 10,000,000 households with leaky faucets. Write a brief report to discuss your findings.arrow_forwardAs we explained in Chapter 10, viscosity is a measure of how easily a fluid flows. For example, honey has a higher value of viscosity than does water because if you were to pour water and honey side by side on an inclined surface, the water will flow faster. The viscosity of a fluid plays a significant role in the analysis of many fluid dynamics problems. The viscosity ofwater can be determined from the following correlation:μ = c1 10c2 1(T−c3 )whereμ = viscosity (N/s.m2 )T = temperature (K)c1=2.414×10-5 (N/s.m2 ) c2= 247.8 K c3= 140 KUsing Excel, create a table that shows the viscosity of water as a function oftemperature in the range of 0° C (273 15 ) to 100° C (373 15 ) in increments of 5° C. Also create a graph showing the value of viscosity as a function of temperature.arrow_forward
