Air flows through the fins and water flows through the tubes of the heat exchanger. Given this data determine the

a. UA product for each of the three air flow rates. Can a simple relationship be developed for the UA product as a function of the air flow rate? If so, deter-mine this relationship. If the manufacturer only provided data for the 1,200-cfm air flow case, deter-mine the

b. Percent error in the UA product that would occur at 1,000 cfm and 1,400 cfm compared to the UA product calculated at 1,200 cfm. Is the variation in the UA product for this heat exchanger significant over the range of air flows given for the application?
