Finned tube design verification
Thread Content
Air is heated using finned tubes; given the amount of heat added to the air and the inlet temperature of the cooling water, how can the outlet temperature of the cooling water be determined once the fin structure has been specified? (This is what I’m thinking: Q=KFT; the heat transfer coefficient can be determined, but what about the heat transfer area?) I hope experts can give some guidance
1. The inlet and outlet temperatures of the air are determined; the heat quantity is calculated using Q=c*m*(t1-t2)； The water inlet temperature is known; based on heat balance, the outlet temperature can be calculated. 2. Determine the heat transfer film coefficient K; then, Q=KFT can be used to calculate the required heat exchange area ； 3. My Penguin: 1711819313. Feel free to contact me if you have any questions.
