| Contd. -2- Hs {Lord Ernest Hives - Chair} 6/T.6.22. We have also checked the inlet and outlet water temperatures at various speeds and temperatures. Below are the results :- | Temperature of inlet. | Temperature of outlet. | |---|---|---| | | 1000 R.P.M. | 1200 | 1500 | | 20°C | 27 | 27 | 27 | | 30° | 38 | 37 | 37 | | 40° | 48 | 47 | 47 | | 50° | 58 | 57 | 57 | | 60° | 67 | 67 | 67 | | 70° | 78 | 77 | 77 | | 80° | 88 | 86 | 86 | | 90° | 99 | 97 | 96 | Engine run full power on bed - fan and radiator fitted. We do not propose carrying out any further tests on the Goshawk(Aero Engine)(Codename for 20HP Car / Aero Engine after Kestrel(Aero Engine)) cooling until we get the improved fan. We do not see how it is possible to improve the circulation. Hs. {Lord Ernest Hives - Chair} | ||
