Problem 11.4: Assuming normal heptane and normal octane to form ideal solutions, do the following: a) Calculate the chemical potential of n-C7 (1) in solution with n-C8 (2) at 40 °C, 1 bar, x1 = 0.45. b) Calculate the fugacity of normal heptane at the conditions of part (a). c) Calculate the bubble pressure of the solution (x1 = 0.45) at 40 °C. d) Calculate the dew pressure of the solution at 40 °C. e) Calculate the bubble temperature at 1 bar. f) Calculate the dew temperature at 1 bar. g) Calculate the amount and composition of vapor and liquid when a solution with z1 = 0.45 is flashed to 40 °C, 0.065 bar.
Burning the coke deposited on the catalyst particles generates all the heat necessary for catalytic cracking. Therefore, the coke burning rate is a critical parameter to control the rate of cracking. The composition of dry flue gas from the regenerat..
The motor starting torque.
Sinusoids of varying frequencies were applied to an open loop system and the following results were measured. (Data is from Seidel, 1975.) Construct a Bode diagram for the data.
Determine the efficiency when the transformer delivers a load of 2 kVA at 0.85 power factor lagging.
If the motor is operating on load with a power angle of -20°, and the excitation is adjusted so that the excitation voltage is equal in magnitude to the terminal voltage, determine the armature current and the power factor of the motor.
Three waveforms seen on an oscilloscope are shown in Figure P1.4.7. If the horizontal scale is set to 50 ms per division (500 ms for the entire screen width), and the vertical scale is set to 5 mV per division (±25 mV for the entire screen height ..
Under what circumstances and for what kinds of disabilities would the CLI be superior to or be preferred over the GUI?
consider the binary cycle using the sodium and steamwater in the sketch below and operating at conditions in table 1.
When algae growing in water containing only 16O were furnished carbon dioxide containing 18O, no 18O was found to be evolved from the oxygen gas produced. What conclusions about photosynthesis can be drawn from these experiments?
