Methods of Experimental Measurement

The washout function also provides the basis for a method of experimentally measuring RTD (Chapter 19 see also problem 13-1). Consequences of the definition of W and its relation to F and E are explored in problem 13-5. 

The methods of experimental measurement of heat and mass transfer coefficients are summarized in Table 4.8, and resulted mainly from heat and mass transfer investigations in packed beds. Heat transfer techniques are either steady or unsteady state. In steady-state methods, the heat flow is... 

During the operation of technological equipment, it is necessary, in order to evaluate its actual technical conditions, to collect data that characterize operational conditions, that is, to apply technical diagnostic methods in alignment with the latest methods of experimental measurement. Furthermore, it is important to verify the data measured as well as the data processing methodology to eliminate their irrelevance to the monitored subject.
