A counter flow double pipe heat exchanger with diameters shown in Figure is used for engine oil cooling. Engine oil at 400 K with flow rate of
6.0(l)/(m)inis cooled by water at 300 K with flow rate of
2.0(l)/(m)in. If the Engine oil is cooled to 340 K , (a) please calculate the both sides heat transfer rate and exit temperatures of water. (
30%) What is tube length required? (Extra 10%)
(kg)/(min)=(L)/(m)in
((kg))/(l)\times (l)/(605)((kg))/((s))
( ?? )/(2)=kg.
