Efficiency of an engine operating condition to Carnot cycle is
equal to ? = 0.45. Temperature and specific volume of the gaseous
working medium at the beginning of isentropic compression are T1 =
600 K and v1 = 0.5 m3/Kg respectively. Find the gas
properties at all other characteristic points of the cycle and the
amount of heat released during isothermal compression. Assume that
the mass of 1Kg of the gas undergoes the sequence of processes
corresponding to Carnot cycle....
4: Consider a vapor refrigeration cycle.
a: Draw the T-s diagram of the reversed Carnot Cycle and describe
what kind of problem each process of the cycle has explicitly. (We
use the mixture of liquid and vapor as its working fluid.)
b: Draw a T-s diagram in the ideal refrigeration cycle and label
each process explicitly. Write down the COP in terms of
enthalpy.
c: There are the multipurpose refrigeration system and the
multistage refrigeration system to improve the ideal...
The figure below provides the T–s diagram of a Carnot
heat pump cycle for which the substance is ammonia, where
x3 = 70%.
Determine the net work input required, in kJ, for 50 cycles of
operation and 0.1 kg of substance.
Note that work is positive going into the heat pump.
Working from first principles, derive an expression for the
efficiency of an Otto Cycle engine in terms of compression ratio.
Sketch the P-V diagram for this cycle and annotate it using the
same station numbers used in your derivation. State why the
efficiency must be less than that of the Carnot Cycle.
Created a chart (any way you would like) include in
the chart if the media is selective,differential,enrichment-any
special characteristics,what is it used for identification,what are
the possible results (and any color changes or any other
ingredients needed to analyze)and what are the interpretations of
those results.
Create a chart ( any way you would like)that summaries
all the medias include in the chart if the media is selective,
differential, enrichment-any special characteristics, what is it
used for identification, what are the possible results ( and any
color changes or any other ingredients needed to analyze) and what
are the interpretations if those results.
Any advice or recommendation would be greatly appreciated
You are the sport agent for a rising basketball star just

You like cookies and you like chocolate. Draw a diagram to show
that it is possible for your optimal bundle to consist entirely of
chocolate. Would it be correct for someone to conclude that, since
you are only buying chocolate, you do not like cookies? Explain
your answer carefully.
