Hs{Lord Ernest Hives - Chair} [struck through] from Mx.{John H Maddocks - Chief Proving Officer} X7250 Mx{John H Maddocks - Chief Proving Officer}6/T12.6.29. "SS{S. Smith}" RADIATOR We have made some comparisons between 23-EX and a Standard Phantom Chassis with regard to loss of water. Each radiator was filled to half-way up the outlet pipe i.e. the usual filling level. The SS{S. Smith} takes 6 gallons 6 pints, the Phantom 6 gallons 3 pints. Each Chassis was raised to boiling point, and was run in this condition for 10 minutes at a 1000 revs. The water was then allowed to cool, and the quantity of water required to bring it up to the original level was put in. The SS{S. Smith} had lost 5 pints of water, and the Phantom 7 pints. Mx{John H Maddocks - Chief Proving Officer} [signature] | ||
