| (2) Graph Text: QUARTS COMMENCEMENT OF GRADIENT. TOTAL LOSS LOSS AS STEAM LOSS AS EJECTED WATER. START 0° 0 MIN 80° 100° A 30 MIN 60 MIN Main Text: NOTE:- "A" IS POINT WHERE WATER EJECTION CEASES. We wish this to be a standard type of test for cooling and would like you to try it for:- (1) Standard 40/50. (2) Standard 20.HP. with louvres wide open (no thermostat tank). Then on the 40/50 we wish you to repeat it with the following modifications:- (a) The water inlet to be as low down in the radiator tank as possible. (b) The water inlet as high up as possible. (c) With an extra tank behind the radiator tank of 3 quarts capacity, and the inlet high up in it. The same quantity of water tobe as standard, there being 3 quarts of space above the water. We shall later be sending further experiments which we shall hope to try on these standard lines. PA{Mr Paterson}/EV.{Ivan Evernden - coachwork} | ||
