A conditioned space has a calculated heat loss at the design maximum heating day of 10,000 BTUs / Hr to maintain an interior temperature of 70 F. We will use a hydronic baseboard style convector to heat the space. The style we have chosen comes in standard lengths. At rated temperature and flow of hydronic heating fluid for each 1 foot of length the heater will add 750 BTUs /Hr to the room. What length of heater can just maintain the temperature on the worst day? For this example we are ignoring other sources of heat loss such as ventilation or drafts.

Part b. MATLAB coding.  Hot air for a large scale drying operation is to be produced by routing the air over a tube bank, while products of combustion are routed through the tubes. The surface area of the cross-flow heat exchanger is A = 25 m2, and for the proposed operating conditions, the manufacturer specifies and overall heat transfer coefficient of U = 35 W/(m2 K). The air and the combustion gases may each be assumed to have a specific heat of cp = 1040 J/(kg K). Consider conditions for which combustion gases flowing at 1 kg/s enter the heat exchanger at 800 K, while air at 5 kg/s has an inlet temperature of 300 K. (a) What are the air and gas outlet temperatures? (b) Explore the effect of changes in surface area and heat transfer coefficient on the air outlet temperature for UA values from 500 to 2500 W/K. Discuss the implications and back up the discussion with an appropriate plot
