Q3. The data listed in the following table gives hourly measurements of heat flux q (cal/cm²/h) at the surface of a solar collector. As an architectural engineer, you must estimate the total heat absorbed by a 150,000-cm² collector panel during a 14-hour period. The panel has an absorption efficiency of 45%. The total heat absorbed is given by:
h = e_ab∫^t_0 q A dt
where A = area and q = heat flux.
t 0 2 4 6 8 10 12 14
q 0.10 5.32 7.80 8.00 8.03 6.27 3.54 0.20
