Dead Weight Perssure Tester

Extracts from this document...

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.
