You are running an experimental fixed-bed adsorption column that enables you to sample the liquid along the length of the bed. These samples then may be analyzed for solute concentration. Based on your analysis, you determine that 60% of the bed comes to equilibrium with the feed solute concentration at breakthrough.
Required:
a. What is the corresponding bed efficiency (fraction of bed utilized)?
b. If the bed performance described above was achieved under conditions where the adsorption isotherm is roughly linear with K = 100, can q be improved to 0.95 by changing K if all else is held constant? Explain.
c. How does the slope of the breakthrough curve change with K? Discuss this issue
with regard to fixed bed adsorption column operation and performance.

Apiping systems consists of 6 m of 6-std type k and 12 m of 4-std type k, both drawn copper tubing. the system conveys ethylene glycol at a rate of 0.013 m3/s. the pressure drop across the system is to be calculated. there are two 90° elbows in the 6-in pipe, a reduction from the 6-in pipe to the 4-in pipe and four 90° elbows in the 4-in pipe. all fittings are soldered (same as flanged) and regular. the inlet and outlet of the system are at the same height.
