Page 169 - Since the purpose of the test was to determine whether or not the results were reproducible, cycle stations were relatively close.
Page 17 - C the corresponding mean pressure is about 3'4 atmos., that is the mean pressure at the point of intersection of the two curves. The point of intersection of the two curves...
Page 20 - ... now these fundamental mistakes are avoided, that is to say, if the counter-flow \ is replaced by a uni-directional flow, the cooling of the...
Page 19 - It may also be seen from consideration of the character of the adiabatic expansion and compression curves, that the una-flow steam engine must give almost the same economic efficiency with superheated as with saturated steam.
Page 3 - Owing to the complete removal of all the moisture at each stroke, the well known heat losses, caused by the presence of water, in ordinary engines are avoided.
Page 141 - With a 2% clearance, cut-off at 5%, condenser pressure 0.07 atmos absolute, the most favourable compression is 90% and these conditions may be taken as normal for the unaflow engine.
Page 126 - ... the cylinder during the latter part of the expansion and the early part of compression.
