MATH AND SCIENCE 2 Task 1 Objective To determine the accuracy of a pressure gauge readings and how to calibrate it. Procedure: 1. The cross-sectional area of the piston, as well as the weight, was noted. 2. The piston was removed then water was poured into the cylinder up to the overflow level. 3. The apparatus was tilted and then tapped gently in order to eliminate any air that was trapped in the tube. 4. The piston was then replaced into the cylinder an then given room to settle. 5. In order to make sure that the apparatus, that is the cylinder, was vertical, the spirit level that is placed on the platform on the top of the piston was used, and necessary adjustments are done. 6. Addition of weights was done in appropriate increments while the pressure gauge readings were observed and noted at every increment. 7. As the pressure gauge was being used, the piston was gently rotated so as to prevent it from sticking to the cylinder. Results Weight of piston = 9.81 N/m 2 Area of piston = 3.15 X 10 -4 m 2 SI.

But the point plotted is not very straight or smoothly linear. Moreover, it can be viewed that the gauge error was not consistent. There are a number of factors that contributed to these results. These include:

MATH AND SCIENCE 4 (i) possibility of trapped air or bubbles within the tube as the experiment was being done (Kajikawa and Kobata, 2016). (ii) Exaction of pressure on the piston in the course of its application placed into the cylinder which can impact the pressure reading gauges obtained from the whole experiment. (iii) There is a possibility that the piston could not be entirely stable in the course of reading the value gauge values. Occurrence of parallax error while reading the pressure gauges in which the eyes of the observer are not normal to the pressure gauge scale (Zhang, Zu, and Pei, 2012). Conclusion: The goal of the experiment which was to determine the pressure gauge accuracy and also to determine its calibration requirements was met.

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
