Abstract

A method for detecting a leak in a fluid conducting conduit is disclosed. Inlet and outlet flowrates are measured for calculating a time derivative of average temperature of the fluid flowing in the fluid conducting conduit. A predicted difference in flowrate between a flowrate of fluid in the fluid conducting conduit adjacent the inlet and a flowrate of fluid in the fluid conducting conduit adjacent the outlet is calculated based on the calculated time derivative of the average temperature of the fluid flowing in the fluid conducting conduit. The predicted difference in flowrate is compared to a difference between the measured inlet flowrate and the measured outlet flowrate to determine whether a leak exists in the fluid conducting conduit.
