One hundred moles per minute of a 50 mol% n-hexane/50 mol% n-pentane liquid mixture at 85 oC and 6 atm is fed to an evaporator. In the evaporator, the temperature is kept at 70 oC by a heating/cooling jacket surrounding the outside of the evaporator tank. The liquid stream of hexane and pentane leaving the evaporator is found to be 65 mol% hexane.
a) Determine the pressure in the evaporator.b) Determine the composition and volumetric flow rate of the vapor stream leaving the evaporator.c) Describe IN DETAIL how you could determine the required rate of heat addition or removal.
You can assume ideal behavior for this problem and that the Antoine coefficients are valid over the entire T range.
how to derive the constitutive expression for stress in a Newtonian fluid. How to derive Navier-stokes equation for compressible, incompressible, and invicid flows.
In order to increase production rate a reactor set point was increased from 160 psig to190 psig. The reactor pressure transmitter was recalibrated from 0-200 psig to 0-300 psig.
Your rich godfather has offered you a choice of one of the three following alternatives: $10,000 now; $2,000 a year for eight yeaers; or $24,000 at the end of eight years
