| E.{Mr Elliott - Chief Engineer} from Hs.{Lord Ernest Hives - Chair} X4240 Hs{Lord Ernest Hives - Chair}2/LG13.5.22. RADIATOR OVER-FLOW OUTLET. We consider, on Goshawks, we shall always have a Thermometer fitted. We think that there is reasonable justification to have a thermometer even with thermostat operated shutters, because the thermometer will show us the temperature throughout the whole system, whereas, when a thermometer is used with a thermostat which only short-circuits the radiator, it only gives the temperature of a part of the system. If we retain the thermometer, then we do not consider we should worry about whether the steam can be seen by the driver. It is very doubtful, when the car is going at any speed, whether it would be seen, even if it was led to the outside. Hs.{Lord Ernest Hives - Chair} | ||
