Abstract

Cans of aqueous solution of Calcium Chloride of various concentrations were placed in a low temperature room at temperatures varying from -6 to -30 deg F. The results confirm data in the Chemical Engineers Handbook by John H. Perry (1934). An 8-in. gage charged to protect an expected 10 inches of precipitation to -20deg F will require an initial charge of 26.9 lb. commercial Calcium Chloride and 35.8 lb. water. The storage precipitation gage is not recommended if the gage must be unattended for month or more at below 0deg F temperatures.
