Mercury is the closest planet to the Sun and the smallest one in the Solar System—it’s
only a bit larger than the Moon. The planet’s name has nothing to do with the liquid metal
Venus has a beautiful name and is the second planet from the Sun. It’s terribly hot—even
hotter than Mercury—and its atmosphere is extremely poisonous
Jupiter is a gas giant and the biggest planet in the Solar System. It's the fourth-brightest
object in the night sky. It was named after the Roman god of the skies and lightning
What about Mercury?
What about Venus?

Solution
Step 1: Convertflow rate to ICFM using 12801.5 ICFM
1st STAGE
Step 2: Calculate Compression ratio (assume one stage) n=1
R (p2/p1)^1/n 6
Step 3: Calculate discharge temperature, T2, 307.1252 ˚F
Use one stage if Overall compression ratio is less than 5 ,Suction gas temperature is under 110°F (43°C)
, discharge temperature is less than 300°F (149°C)
For n=2
R 2.44949
Td 167.3239 ˚F
Step 4: If Step 4 indicates that intercooling is not necessary, refer to Fig. 7.24 and select the type of compressor.
Assuming CENTRIFUGAL COMPRESSOR ,so a/c to polytropic process
Step 4: The polytropic head can also be determined from the following equation:
Hp 52404.37 ft lbf/lbm
Step 10: Calculate weight flow using Eq. (7.15) and assume that this value is con stant for all compression steps
w 980 lb/min
GHP 1945.3
Step 6: The polytropic break horsepower (BHP), which accounts for mechanical losses
BHP 1309.378
Step 7: Adiabatic head can also be written as follows:

Step 6: If the temperatures cited in Step 4 are exceeded, more than one step of compression will be required
Use 3% allowance for pressure drop between the steps

SIZING OF JT-
VALVE
Chokedflow (Critical Flow) is a
phenomenon in fluid dynamics
where the mass flow rate of a fluid
passing through a restriction reaches
a maximum value, and further
decreasing the downstream pressure
does not increase the flow rate.
