Introduction

DEAD WEIGHT PERSSURE TESTER 1) DESCRIPTION OF EOUIPMENT The equipment comprises a precision machined piston and cylinder, and weights may be added to the piston so that a number of predetermined pressures may be set up within the cylinder. The cylinder is screwed on to a base plate supported on leveling screws and the base plate is fitted with a bull's eye level. Weights supplied are 2 x 2.0 + 2 x 1.0 + 1 x 0.5kg.Piston weight is 0.5kg. ...read more.

Middle

P = pressure kg/cm� or other unit F = force kg or other unit A = ? D� 4 = piston cross section area =250mm� =2.5cm� Exact diameter of the piston is indicated on the piston. This pressure P is transmitted to the pressure gauge and comparison between actual pressure and gauge reading can then be made. 3) TEST PROCEDURE a) Firstly, placing the pressure gauge on the tester and ensure that the connection is tight. ...read more.

Conclusion

Plot graph of gauge reading versus absolute gauge error and graph of gauge reading versus percentage gauge error. g) what ate the sources contributing to error of this experiment? Piston Weight (kg) Pressure In Cylinder = Piston weight area ( kg/cm�) Gauge Reading ( kg/cm�) Absolute Gauge Error ( kg/cm�) % Gauge Error Gauge Error x 100 Actual pressure 0.5 0.2 0.15 0.05 25.00 1.0 0.4 0.41 0.01 2.50 1.5 0.6 0.61 0.01 1.67 2.0 0.8 0.80 0.00 0.00 2.5 1.0 1.00 0.00 0.00 3.0 1.2 1.15 0.05 4.17 4.0 1.6 1.50 0.10 6.25 5.0 2.0 1.90 0.10 5.00 6.0 2.4 2.40 0.00 0.00 ...read more.

* Bias - Although the questionnaire is completed in a consistent fashion, this consistency may contain bias (e.g. the interviewer consistently misinterprets an answer, or gives misleading guidance). * Lack of anonymity - a respondent may refuse to answer questions because o being embarrassed by the presence of the interviewer.

2. ## The comparison between Football, Javelin and Weight lifting.

This means that footballers are obviously going to need a lot more cardio-vascular endurance because they are taking part in a much more dynamic and therefore more aerobic sport. Also in football there is more than one skill involved, for example the player must be able to defend and attack else they will never be a very successful central midfielder.
