To Py/BLB. from Hs.{Lord Ernest Hives - Chair} c. to RG.{Mr Rowledge} EAGLE - WATER FLOW & HEAT LOSS TO COOLING WATER. Y3036 Kru#8 Answering your Py/BLE2/AV/D27.11.25. We give the required data herewith. Eagle water pump delivery at 1700 r.p.m. = 40 galls/min. " " " " " 1750 r.p.m. = 41.2 " " " " " " " 1800 r.p.m. = 42.5 " " The difference in temperature between the water entering the pump and leaving the engine = 12°C. Therefore the heat loss to cooling water is :- At 1700 r.p.m. flow 40 galls/min temp.diff 12°C = 8640 B.THUs/m.{Mr Moon / Mr Moore} " 1750 " " 41.2 " " " " = 8899 " " " 1800 " " 42.5 " " " " = 9180 " " The average B.HP. at the above r.p.m: = 1700 342 B.HP. 1750 350 " 1800 360 " with the throttle fully open. We trust the above information is what you require. Hs.{Lord Ernest Hives - Chair} | ||
