Abstract: The time for gravity draining of water from a large Cylindrical open tank by means of a drain pipe ( Located at the center of the bottom of the storage tank) is measured experimentally for the case of turbulent flow conditions in the drain pipe. Further, to reduce draining time, experiments are also conducted by the addition of water soluble Carboxymethyl Cellulose (CMC). The concentrations of CMC considered are 0.625,1.25, 2.5 and 5ppm respectively. The optimum concentration of CMC is found to be 0.625 ppm. Further, the re-usability of CMC polymer solutions is also contemplated and it is noted that there is an increase in draining time upon re-use of the CMC polymer solutions.
