| X 116. E.{Mr Elliott - Chief Engineer} from Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer} Hs{Lord Ernest Hives - Chair}/Rm.{William Robotham - Chief Engineer}10/KT.3.3.33. PEREGRINE OIL SYSTEM. Referring to E.1/HP.20.2.33., E.1/HP.23.2.33., and E.9/HP.15.2.33. We have run the bottom half with the jets impinging on it in each compartment, the results being a definite gain of about 10°C. Calculations shew that we do require increased cooling ribs on the bottom half. Probably these would be no use unless the oil flow was turbulent. With regard to the delivery of the oil pump, we do not hold the opinion of GWH.{George W. Hancock - Head Chateauroux} that the quantity of oil circulating has any undesirable effect on the heat to the oil. On the contrary, if the pump delivery is utilised to promote turbulence, it would seem most undesirable to reduce the size of the pump. We will, however, measure the flow of oil through the bearings.
