What is the basis for System III on Figure 3.1?

Determine a basis for each of the systems in Figure 3.1. Solution: In System I, a mass flow rate of 100 g/hr is given for stream 1. Therefore, the basis of 100 g/hr is selected for System I to solve for the flow rates of streams 2 and 3, as well with the s the flow rates of the individual components A and B in all three streams. In System II, the mass flow rate of compound A in stream 1 is given. We can use this flow rate of 1 g/s of compound A in stream 1 as the basis for all other calculations. In System III, no amount or flow rate is given. However, the mass fraction serve as the A is given in streams 1 and 3. We can choose either stream-but not both-to flow rate basis. For example, we can arbitrarily define our basis such that stream 3 has a mass flow rate of 10 lb_m/hr. Therefore, the flow rate of compound A in stream 3 is 5 lb_m/hr. We could also have chosen a basis of 100 lb_m/hr for stream 3. In this case, all of the calculated flow rates to the would have been a factor of 10 higher. Note that the ratios of any two streams each other constant. This is an example of how the results can be scaled.

Explanation / Answer

Law of Thermodynamics. zeroth law of thermodynamics is the basis for System III on Figure 3.1. Because thetre are A and B;two systems are in thermal equilibrium with a third system C; it means they are in thermal eqquilibrium with each other
