Precalculations Consider the quasi-steady, incompressible energy equation for flow from the reservoir surface, through the sudden contraction and ball valve, and through the capillary tube, as sketched in Figure 1 of the Equipment section. The term “quasi- steady” refers to the assumption that the liquid level in the reservoir is essentially constant, thereby eliminating all of the time-dependent terms in the full form of the energy equation. Also, we recognize that the inlet and/or outlet may not be one- dimensional, and thus, the kinetic energy correction factor α is included to account for the non-uniform velocity profile. For the case of one inlet and one outlet, the steady, incompressible energy equation in head form is given as follows: 2 2 pump viscous turbine 11 22 2 2 , total L W WW PV P V zz g g mg mg g g mg αα ρρ ++ =+ + + + & && & h
