PlVc Pi +7- The area = a maximum when log, Vi = log* v2 — 1 + Let pi=14.7, d2 = 1, ?v = .03, log, ii =0-1 +.03= -.97.(Add 2.3025 and we obtain 2.3025-.97 = 1.3325, or the logarithmof ten times the required number, .*. Fi = .379.) Hence the jarea is a maximum when Vi = .379. The corresponding value… … Fig. 143.Edwards Air-pump.—The condensed steam flows continu-ously by gravity from the condenser into the base of the pump 272 THE STEAM-ENGINE AND OTHER HEAT-MOTORS. and is there dealt with mechanically by the conical bucket workingin connection with a base of similar shape.
