In this HW, you will learn to perform:
• Steady state mass balance
• Evaluation of ideal gas volumes
• Use of steam tables (saturated vapor/liquid, compressed liquid, superheated vapor) to evaluate steam properties.
1. In this problem, you learn how to apply the energy balance to a closed system containing an ideal gas with constant Cp for 3 different processes.
2. (i), (c) & (d). Just do 50 % evaporated.
Here you compare the value of H when you use actual data (steam tables) and when you assume ideal gas. Reference means H = 0. State all reasonable assumptions. Vapor-liquid phase partitioning is involved.
3. Here you perform an energy balance for an adiabatic turbine using steam.
4. (b)Here you do a process analysis for an unsteady state problem. You may need to use iterative solution (you need only perform 2 iterations and then perform a linear interpolation).
5. This is a simple energy balance on a steady state reactor problem.
Consider the situation described in Ex. 3.4. The reaction is
2 H2 + CO = CH3OH
This reaction takes place in an adiabatic, steady state flow reactor.
The inlet moles are as given in Ex. 3.4.
(a) Let the inlet temperature be 350 K. If the outlet temperature is 450 K, calculate the moles of CH3OH formed in the reactor.
(b) Suppose we wish to keep the reactor isothermal (the outlet is 350 K also) and 0.5 moles of CH3OH is formed in the reactor, how much heat must be removed?
1. This problem deals with analysis of thermal efficiency of cyclic processes.
2. This problem estimates the potential to do work (this case destructive work) of compressed gases.
3. This problem illustrates the application of S balance to a heat-exchanger, and the issue of S generation.
4. This problem requires an analysis of a 2-stage compressor with inter-stage cooling. Let the inlet of stage I be point 1, outlet of stage I ( and inlet to the heat-exchanger) be point 2, let outlet of heat-exchanger (and inlet to stage II) be point 3; let point 4 be exit from stage II.
Note: you are using methane (not steam), so the properties must be obtained from a data source (in this case use the methane p-H chart in Appendix E-10).
5. In this problem, you are required to analyze a steam turbine, when it is reversible as well as when it is irreversible (mechanical efficiency < 100 %). Since it is a steam problem, use steam tables for the properties.
