SINOPSIS

A mathematical equation for efflux time for slow draining of a Newtonian liquid from a large cylindrical tank through an exit pipe located at the bottom of tank when the flow in the pipe line is turbulent is developed based on macroscopic balances. The equation is fine tuned with the experimental data and an empirical equation for friction factor is developed. The efflux time equation so developed will be of use in arriving at the minimum time required for draining the tank. When the flow is partly laminar and partly turbulent, gravity driven and once through (as is the case in the above), the effect of addition of water soluble Polyacrylamide polymer on drag reduction is expressed in terms of % reduction in efflux time. Based on the efflux time, an empirical equation for friction factor is developed. The concentration of polymer which gives maximum drag reduction is also established.
