Chapter 11.4, Problem 38E

(a)

To determine

To calculate: The concentration of the fluid a s a function of time t when a tracer inject at a rate of $2\text{mol}/\min$ for a flow rate of $0.5\text{L}/\min$ and the volume of the fluid is $2\text{ litres}$. The concentration of the fluid in the compartment start to dilute by the differential equation $\frac{dC}{dt}=\frac{Q}{V}-\left(\frac{R}{V}\right)C$ where $Q$ is the moles per minute and $C=0$ when $t=0$.

(b)

To determine

To calculate: The concentration of the fluid a s a function of time t when a tracer inject at a rate of $1\text{mol}/\min$ for a flow rate of $1.0\text{L}/\min$ and the volume of the fluid is $2\text{ litres}$. The concentration of the fluid in the compartment start to dilute by the differential equation $\frac{dC}{dt}=\frac{Q}{V}-\left(\frac{R}{V}\right)C$ where $Q$ is the moles per minute and $C=0$ when $t=0$.
