EXPERIMENTAL STUDY OF PISTON ROTATION RATE EFFECT

O. Ott, W. Sabuga, T. Konczak

Abstract

The effect of the piston rotation rate on the gauge pressure measured by deadweight pressure balances was experimentally studied. Experiments were performed with a PTB twin primary gas pressure balance and several commercial gas and oil operated pressure balances with different configurations and size of rotating weights. It was found out that the piston rotation effect significantly depends on the distance between the horizontal surface of the rotating weights and the nearest fixed surface of the pressure balance.
