Also that the capacities at these two points for each condenser, appreciably agree. There appears then to be some relation between capacity and the leakage point. It seems that the capacity of a condenser must either go on increasing with repeated heatings until it breaks down, or the amount of increase diminish with each cycle until a point is reached where it is stabilised, and the capacity varies within that range of temperature without receiving a permanent "set". It would also be interesting to confirm whether or not there is a point above which the condenser receives a permanent increase, or whether it receives a slight increase with every little rise in temperature. Finally whether leakage is entirely a question of heat, or whether it occurs on the condenser receiving a specific increase in capacity. Signed C.A.P. This Sheet must be filed on completion of the work. | ||
