(a) How many balance equations can you write? How many of those are lin-\ early independent?\ (b) Calculate the flow rate of the process stream containing

95mol%N_(2)

and\

5mol%O_(2)

.3.4 One method to determine the flow rate of a turbulently flowing stream is to in-\ ject a small, metered amount of some easily dispersed fluid and then to measure\ the concentration of this fluid in a sample of the mixed stream withdrawn a\ suitable distance downstream. In pharmaceutical plants, there are often many\ inert gas streams (i.e., streams that contain mostly nonreacting gases). In a par-\ ticular plant, there is a process stream that is composed of

95mol%N_(2)

(inert)\ and

5mol%O_(2)

. To determine the flow rate of this process stream,

O_(2)

is in-\ jected at a flow rate of

16.3mo(l)/(h)r

. A downstream sample analyzes the

O_(2)

\ content at

10mol%

. You can assume that no reactions occur in the pipe and\ that the flows are operating at steady-state.

3.4 One method to determine the flow rate of a turbulently flowing stream is to inject a small, metered amount of some easily dispersed fluid and then to measure the concentration of this fluid in a sample of the mixed stream withdrawn a suitable distance downstream. In pharmaceutical plants, there are often many inert gas streams (i.e., streams that contain mostly nonreacting gases). In a particular plant, there is a process stream that is composed of 95mol%N2 (inert) and 5mol%O2. To determine the flow rate of this process stream, O2 is injected at a flow rate of 16.3mol/hr. A downstream sample analyzes the O2 content at 10mol%. You can assume that no reactions occur in the pipe and that the flows are operating at steady-state
