4) the latter equation embodying the condition of symmetrical reversal, and being subject to modification in the actual case. The effective impulses are now W W Fl==lLUl and f2 = - U2, Q 9 and the work rate is W W p = VL T (Ux + U2) = 2 — (UT - T2). Q 9 (225) Examining this for the maximum value of… … D x E F C T Fig. 315. — Velocity Diagram for the Reaction Element. velocity of the steam jet for maximum efficiency. The greatest workrate is now W 1 1 W (227) or, as it should be, the full kinetic energy available in the weight W ofsteam that passes in one second. (h) Work in the Reaction Turbine.…
