Document Summary
Flow in closed conduits (cid:1) objectives: to estimate head losses in closed conduit. (cid:1) outline (cid:5) 1: darcy#weisbach equation, formulas for estimation of friction factor and moody diagram, three types of problems in pipe#flow calculations: Examples: head loss due to a sudden contraction, general form of minor loss equation, examples. Hw#10 (due on dec. 4: textbook problems: Flow in closed conduits: a conduit is any pipe, tube, or duct that is (cid:1)(cid:2)(cid:3)(cid:4)(cid:5)(cid:6)(cid:7)(cid:6)(cid:5)(cid:8) filled with a flowing fluid, a pipe that is (cid:4)(cid:9)(cid:10)(cid:7)(cid:11)(cid:9)(cid:5)(cid:5)(cid:8) filled with a flowing fluid is classified as an open#channel flow. A piping system consists of the pipes, fittings, control valves, etc. Frictional losses: the head losses resulting from friction between the moving water and the walls of the pipe. Minor losses: the head losses resulting from changes in pipe diameter and the cross#sectional area of the flow, pipe bends and fittings (for example valves and junctions).
