| Contd. -2- 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. | |---|---|---|---| | | 1600 | 1800 | 2200 | | 20°C | 27 | 27 | 27 | | 30° | 36 | 37 | 37 | | 40° | 46 | 47 | 47 | | 50° | 56 | 57 | 57 | | 60° | 67 | 67 | 67 | | 70° | 76 | 77 | 77 | | 80° | 86 | 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 cooling until we get the improved fan. We do not see how it is possible to improve the circulation. Hs.{Lord Ernest Hives - Chair} | ||
