Summary of photobioreactor and greenhouse parameters.

Parameter	Value	Depends upon	Reference
Diameter of tubes	0.12 m	Larger diameter pipes can cause cell shading	[3]
Spacing of tubes	0.3	Greater spacing is desirable to avoid shading	[13]
Flow rate (𝑄)	3.4 × 10^−3 m^3/s	Algae species and tube diameter	[21]
Recycle Ratio (𝑟)	0.35		[20]
Total volume of reactor (𝑉)	366 m^3	Maximum residence time (30 hrs)	[12]
Influent concentration (𝐶𝑖)	1.2 kg/m^3
Max. Effluent concentration (𝐶𝑒)	3.4 kg/m^3	Growth rate, PBR set up	[13]
