Question 14 Compare the values of the %Recovery obtained in Table 2, from the same ACCURATE SAMPLE chromatogram, under the two treatments: internal and external standard calibration. What can you blame for the difference between the two calculated % Recovery values? Errors that occurred after the internal standard substance arrived in the sample and standard preparations. These include both human and instrumental errors. Errors that occurred before the internal standard substance arrived in the sample and standard preparations. These may be only human errors. Errors that occurred throughout the entire execution of the experiment. The internal standard analysis compensates for errors, so the errors could only come from the external sample.

2. A mass $m_r$ moves about a large planet with a mass $m_1$ in an orbit due to the force of gravity. a) Write the kinetic energy T, the potential energy V due to gravity and construct the Lagrangian b) Use Lagrange's equations to construct differential equations of motion for $r$ and $\theta$. Are there any constants of the motion (conserved quantities)? How do you know? c) Using conservation of angular momentum, and substituting in $r = \frac{1}{u}$, show that the equation of motion that you got for $r$ reduces to a harmonic oscillator equation for $u(\theta)$. Here $m$ is the reduced mass. Hint: $r = \frac{1}{u}$ $L = mr^2\dot{\theta} = m\dot{\theta}\frac{1}{u^2}$ $\dot{\theta} = \frac{L}{mu^2}$ $\frac{dr}{dt} = -\frac{1}{u^2}\frac{du}{dt} = -\frac{1}{u^2}\frac{du}{d\theta}\frac{d\theta}{dt} = -\frac{1}{u^2}\frac{du}{d\theta}\frac{L}{mu^2} = -\frac{L^2}{m}\frac{du}{d\theta}$ $\frac{d^2r}{dt^2} = -\frac{L^2}{m^2}\frac{d^2u}{d\theta^2}$ where $L$ = angular momentum d) Solve for $u(\theta)$ e) Write and sketch the effective potential and discuss the possible motions for different energies. Remember that there is the centripetal barrier piece: $V_c = \frac{L^2}{2mr^2}$. Calculate the equilibrium radius and the frequency of small oscillations. Hint: You will need to take derivatives of the effective potential.

2. What depth of flow can one expect using a 4-ft wide contracted rectangular weir whose crest is 2 ft. off the channel bottom and the discharge is 25 cfs? $C_w = 3.33$ 3. A channel is known to produce a peak flow rate of 0.45 m³/s. The upstream depth must not exceed 2.25 m. If you have a 1.5 m wide end contracted rectangular weir, how high should it be placed in the channel so as not to exceed the 2.25 m upstream depth? $C_w = 1.84$ 4. The maximum depth above the crest of a 60° V-notch weir is 2 ft. What is the maximum discharge that can be measured using this weir? $C_w = 1.44$
