Abstract: A method for determining the sonic velocity in a fluid as a function of pressure and temperature is described. The method used measures the time required for an expansion wave to travel a ...

Abstract: A standard volute-type, radial-flow, centrifugal pump was instrumented to obtain the pressure distribution in the volute and also the bearing reactions from the pump hydraulic force transmitted ...

Abstract: This paper explains the development of a decision tool to assist in determining if investments should be made to replace rod pumps which have failed in marginal oil wells. The paper is ...
