On the Estimation of the Time Required for Emptying Cylindrical Reservoirs Connected to Pipes

The problem investigated in this paper is the accurate evaluation of the time required for emptying a reservoir of constant cross-sectional area in which a pipe is fixed.In the analysis, a friction coefficient equation is considered which represents the different flow regimes on a Moody diagram sati...
