EVAPORATIVELY COOLED PHANTOM II ENGINE AS A POWER UNIT IN 'TANKS' With reference to F's memos 5.10.29 and 24.10.29, in connection with the above subject, I have made a preliminary investigation into the above scheme and would suggest something on the lines outlined in this note. The actual arrangement of the cooling plant depends upon the shape of the tank and other requirements not known by us at the moment. The attached diagramatic arrangement is based upon the preliminary investigation and is intended as a guide from a talking point of view. General Peck's queries as to the sizes of condenser and steam pipe may be answered tentatively as follows :- Min. Frontal area of condenser, 1.25 sq. ft. Dia. of steam and water pipe from engine 1 1/2 ins. Preliminary calculations. Date. All the cooling air must be induced to flow through the condenser tubes by an engine driven fan. The cooling plant must be of minimum bulk, the inlet and outlet of the cooling air being masked. | ||
