A 100 foot long horizontal pipeline transporting benzene develops a leak 43 feet from the high-pressure end. The diameter of the leak is estimated to be 0.1 inch. At the time, the upstream pressure in the pipeline is 50 psig and the downstream pressure is 40 psig. Estimate the mass flow rate of benzene through the leak. The specific gravity of benzene is 0.8794.
