at the end of the expansion will therefore be i^.c,.,A X 250 = 336 feet per second. The mean peripheral velocity of the blades in thesecond expansion will be slightly greater owing to the increased bladeheights. The mean diameter is 66-35 + 133 = 67*68 ins. 67-08 X 340 Vt = ^^^,\ = 100*5 ft per… … W 59 42 30 Absolute Pressure, LbySq. In. Fig. 464. Number of Stages.—The number of stages required in each ex-pansion can be determined by dividing the heat drop per expansionby the work done per stage. A velocity diagram may be drawn foreach stage and the work done may be calculated. Instead of…
