If cin = cb (1 - e-0.12t), calculate the outflow concentration of a conservative substance (no reaction) for a single, completely mixed reactor as a function of time. Use Heun's method (without iteration) to perform the computation. Employ values of cb = 40 mg/m3, Q = 6 m3/min, V = 100 m3, and c0 = 20 mg/m3. Perform the computation from t = 0 to 100 min using h = 2. Plot your results along with the inflow concentration versus time.
from the scattering of sunlight, J. J. Thomson calculated the classical radius of an electron as having the value 2.82 ×10-15 m. Sunlight with an intensity of 500 W/m2 falls on a disk with this radius.
