X766 To R.{Sir Henry Royce} from Hs{Lord Ernest Hives - Chair}/Rn.{Mr Robinson} Copy to Sg.{Arthur F. Sidgreaves - MD} Wor.{Arthur Wormald - General Works Manager} " " BY.{R.W. Bailey - Chief Engineer} Da.{Bernard Day - Chassis Design} E.{Mr Elliott - Chief Engineer} " " OY. Hm.{Capt. W. Hallam - Head Repairs} Hs{Lord Ernest Hives - Chair}/Rn{Mr Robinson}3/BE7.8.29. X7250 X766 S.S. RADIATORS. We have made a careful comparative test of the 6/7 m.m. tubes and the 5 1/2/7 m.m. tubes on the S.S., and the results show that there is no measurable difference in the cooling capacity of the radiator with the tubes giving the wider water spaces. We therefore recommend that these tubes should be used for the S.S. and for all replacements in the case of radiators having integral shutters and tubes 4.25" long.
