The results of the Liberty condenser are interesting showing as they do, very little variation or disturbance with temperature, except at the highest temperatures. 40/50 Mica Condenser. The results of this condenser are also interesting, showing practically no variation except a very slight capacity temperature coefficient. For some curious reason it appears that R.R. 20 H.P. condensers which are originally high in capacity are affected by temperature more in proportion. It will be remembered from our previous report that the U.S.A. Bosch condenser of large initial capacity was affected more proportionally than our own condensers. Generally speaking, in regard to our 20 H.P. condenser, we have arrived at the following conclusions. For any condenser at a given time, taken merely through an atmospheric range of temperature, there appears to be a fairly well defined capacity-temperature coefficient, i.e. the condenser appears to have a definite capacity-temperature curve for atmospheric variations. There is a tendency, however, particularly if the condenser has recently been heated, for this curve to fall bodily when the condenser remains at average atmospheric temperature, Contd. | ||
