The operational amplifier used in the circuit below has an open-loop gain of Avo = 4200 V/V, an input resistance of Rin = 150 kΩ, and an output resistance of Rout = 250 Ω. Using the practical op-amp model, calculate a) the output voltage Vout (8 points); b) the closed loop voltage gain Av (8 points), c) the differential voltage vd (8 points); d) the input resistance seen by the 2.5 V source rin (8 points), and e) the output resistance seen by the 8 kΩ load rout (8 points). Ans: a) Vout = 9.989 V; b) Av = 3.996 V/V; c) vd = 2.601 mV; d) rin = 144.156 MΩ; e) rout = 246.963 mΩ.

Question 1: An advanced catalytic combustor is to be fed a premixed methanol/air gas stream containing 20% excess air, made by passing the air through a bubble-column \"saturator\" containing liquid methanol. The stream (at ambient pressure) gains methanol in the unit and leaves with a methanol vapor composition in equilibrium with the liquid methanol. a) If the combustor requires 4 mole/minute of methanol, what will be the molar flowrate of feed air? b) What temperature do you recommend for the saturator to produce the desired gas composition? c) What model would you use to determine how much air is in the liquid methanol? Explain your answer. Note: for methanol, $\log_{10} [P_{sat} (T(^{\circ}C), in mmHg)] = 7.87863 - \frac{1473.11}{(T + 230.0)}$ 1 atm=760 mmHg

The beam shown in Figure 2 (cross section not to scale) is constructed from two boards. It is subjected to the loading shown in Figure 2. a. Draw the shear force diagram and the bending moment diagram for the beam and show clearly all important values. b. Find the maximum value of shear stress in the beam and state precisely where this occurs. c. Specify the maximum spacing of nails needed to hold the top board in place for each section (AB and BC) if each nail can safely resist 1.5 kN in shear.
