What is the proper concentration unit of kLa?(a) h^-1(b) ml/h(c) mmol/h(d) ml/secI had been asked this question by my school teacher while I was bunking the class.My doubt is from Measurement of KLa in division Mass Transfer of Bioprocess Engineering

Answer»

Right option is (a) h^-1

For EXPLANATION I would say: In this relation, the volumetric oxygen transfer COEFFICIENT, kLa, has the UNITS of mmol, of O2/ml. h. unit concentration GRADIENT. Using the proper concentration units, kLa has the unit of reciprocal of time (i.e., time^-1).
