We have carried out experiments as requested by you in your note R3/LB21615 to obtain the amount of deflection vertically of the crinkled tube radiator by loading on top, also by filling with hot water and measuring the expansion. The top of the radiator (22" X 5") was loaded and the distance between the top and bottom tanks was carefully measured. With 100 lbs the deflection was .004" " 200 " " " .009" " 300 " " " .014" " 400 " " " .025" " 500 " " " .025" " 600 " " " .030" The side plates were removed during the test and the bottom tank was supported all along on a piece of timber. The results were practically the same when the bottom tank was supported at the ends where the ball supports are. The second test was made by running hot water through the radiator and measuring the vertical expansion. The expansion when the water was raised from 15ºC to 97ºC was .031" the temperature of the water being measured at the outlet. It would therefore appear that a deflection of .031" occurs [Watermark: COPY OF AN ORIGINAL] | ||
