Question

A small satellite being designed requires a nitrogen storage tank to store propellant for the cold gas thruster used to maintain the satellite's orientation. The requirements call for 50.0 kg of N2 to be stored in a rigid container at 5°C and 65.0 bar when the satellite is deployed in space. Assuming that nitrogen is an ideal gas, what is the minimum required size (i.e., volume) of the storage tank? While the satellite awaits launch, it is estimated that the temperature in the tank could reach as high as 45°C. If this happens, what will be the maximum internal pressure that the storage vessel must be able to handle (again, assume nitrogen is an ideal gas)? Finally, use equation of state information about "real" nitrogen gas to to estimate the error in the size of the storage tank you originally calculated (i.e., based on the assumption that nitrogen was an ideal gas.

Answer 1

Answer ;

Minimum required volume = 0.635m3

Maximum internal pressure = 74.35bar

Step-by-step explanation:

The detailed step by step calculation using the vanderwaal's equation of state for ideal gases is as shown in the attachment.
