Steam condensing on the outer surface of a thin-walled circular tube of diameter = 50 mm maintains a uniform outer surface temperature of 100C. Water flows through the tube at a rate of m= 0.25 kg/s, and its inlet and outlet temperatures are Ti= 15C and To=57C. Determine the total tube length if average convection coefficient is 753 W/m2K.

The dose-response for a specific drug is \( f(x)=\frac{100 x^{2}}{x^{2}+0.34} \), where \( f(x) \) is the percent of relief obtained from a dose of \( x \) grams of a drug, where \( 0 \leq x \leq 1.5 \). Find \( f^{\prime}(0.5) \) and select the appropriate units. \( f^{\prime}(0.5)= \) \( \square \) Select an answer

1. Explain the difference between the equivalence point and the endpoint in an acid/base titration. (2 pts) 2. If the endpoint in the titration of the HCl with the NaOH standard solution is overshot (too pink), what effect does this have on the calculated molar concentration of the HCl solution? (2 pts) 3. Why is it important for the buret to be conditioned before use? (2 pts) 4. Why are air bubbles in the buret tip a source of error in a titration experiment? How do you remove air bubbles from the buret tip? (2 pts)
