Problem 6.4:
You are in charge of a unit that produces two streams, A at 600 °C, 10 bar, with molar flow rate 100 mole/s; and B at 200 °C, 20 bar, with molar flow rate 50 mole/s. Those streams are currently throttled to 1 bar. An engineer in your team comes to you with an idea to utilize these streams to produce heat and work. She believes she can extract 1700 kW of work and 220 kW of heat that will be used to boil water at 1 bar. Her process, whose details are yet to be determined, will receive streams A and B as inlet and will have a single outlet stream that will be delivered at 1 bar. a) What is the temperature of the exit stream? b) Should you take this idea to your manager for further discussions? c) Could you use the heat from this process to boil water at 10 bar? Additional information: Assume the exhaust gases can be treated as an ideal gas with CP = 30 J/mole K.
Additional data: Use the Lee-Kesler graphs for enthalpy and entropy. The saturation pressure of propane at -51.4 °C is 0.66 bar. Take the ideal-gas CP of propane at these conditions to be constant and equal to 67 J/mole K.
A 1-liter container of nitrogen gas (N2) at a temperature of 23c is intially at a pressure of 1.25 atm. because of a slow leak the pressure falls to 1.15 atm 1 hour later what is the leak rate in molecules/second?

The reaction A + B ? R is a zero order with respect to both A and B. Compute the values for CA and CB at t = 15 seconds if the specific rate of reaction is 0.01 mole/L-s and initial concentration of A and B are both 0.2 moles/L.
