Problem 4.20:
A Carnot cycle operates in a closed system using steam: saturated liquid at 20 bar (state A) is heated isothermally until it becomes saturated vapor (state B), expanded by reversible adiabatic process to 10 bar (state C), partially condensed to state D, and finally compressed by reversible adiabatic process to initial state A. a) Obtain the properties (T, P, V, U, H, and S) at the four states, A, B, C, and D, and summarize the results in a table. b) Calculate the amount of heat and work involved in each of the four legs of the process. c) Calculate the net amount of work that is produced. d) Calculate the ratio of the network over the amount of heat absorbed at the high temperature of the cycle. How does this value compare to the theoretical efficiency of the Carnot cycle that is calculated based on the two operating temperatures?
Calculate the fraction of water that is condensed from the air, the relative humidity of the air at 100°C, and the ratio m3 outlet air at 100°C/m3 feed air at 90°C.
Five different batches of a commercial plastic are sampled to determine the variation of inert additives between batches. Since each batch consists of several thousand pounds of material, several samples are taken from each batch to determine the ..
Carolina (H2C=CHCHO) is made by selective oxidation of propylene at 2 bar, 350 °C using a molybdenum, iron, and bismuth catalyst on a silica support
For this assignment you will undertake an analysis based on a self-designed fictitious study that utilizes statistical analyses. You will first develop a fictitious problem to examine. It can be anything.
