rding friction, ab = bc = ed, bd2 = ab2+eb2-2(ebxef), ae2=ab2+eb2+2(ebxbg), bd2 = ae2~2(ebxbg) -2(ebxef), bd2 = V22 = V2 ~2v(Vi cos a +Vi cos /?), V22 = V2 -2^-(cos a +cos /?). Maximum Efficiency under Various Conditions. — 1. If the stream is turned through 180° both a and /? will be zero,… … Fig. 237. 2. As a rule, it is not feasible to have a = /2 = 0. When V£,a, and /9 are fixed, V2 has a minimum value when {vV%) is a maxi-mum. If Vs and a are fixed in amount, a circular arc can be 456 THE STEAM-ENGINE AND OTHER HEAT-MOTORS. passed through a, b, and e, since we have given a chord and…
