I have a case. I have two tanks, one is filled with Helium gas and monomethylhydrazine(MMH) and another tank with Helium gas and Dinitrogentetraoxide(MON). Both tanks are at 47degC so they are in gaseous form.
I want to know what will be the Molecular Mass of the gas. The...
I would like to ask if we plot the Roll data of a satellite in degrees vs. the time, and if we take the area under the curve of this roll will give something meaningful?
Looking forward for your reply.
I want to know the formula to extract the longitude of the satellite from the TLE below.
I hope someone can help.

Whenever there is a solar activity two things are mentioned, SPE, CME and X-ray. Does anyone know the difference between SPE and CME? I couldn't find a descriptive or convincing answer on these two. What particles are associated with CME, is X-ray a part of CME? And what effects could...
I am trying to find the Absorbed dose for Silicon cells on a geostationary satellite from a period of (1996 to 2005)
The Equation I have is:
D(rad) = 1.68e-8 *((1/ρ)*dE/dx) * Phi
Where: D is absorbed dose and units are (100 ergs/g or 0.01 J/Kg)
(1/ρ)*dE/dx = (MeV*cm^2)/g...
I want to design a Full motion Antenna. But I want to start from the scratch.
Suppose I have a 1m parabolic Antenna and I want to install two motors (Elevation and Azimuth)
The motors should be DC. And I want to know how to calculate all the parameters required to move the...
May be someone can help me with this problem.
There is a isa-chrome60 wire (d=0.5 mm, tensile strength=600 N/mm^2) which is held at both ends using end connectors ( length of the wire = 20mm). And there is a nylon wire (d=0.5 mm) which is under tension (because of torsion spring)...
I am having a design problem. I want to melt a fishing line which is in contact at a single point with some material. The problem is that I have a 5 V of supply and Power should be between 1-3W. Some other constraints are that the material to which the fishing line is connected should be...
I want to convert thermal conductivity to thermal conductance. The problem is with the units.
for thermal conductivity the units are [W/(m.K)] and for thermal conductance the units are [W/K]
For E.g for copper thermal conductivity is 400[W/m.K]
how can I convert it to thermal...
I am designing the solar panel deployment mechanism using torsion springs for a satellite. I have a few questions to ask here and appreciate if someone could help:
1. How can I calculate the Force required by torsion spring to open the panel?
( mass of panel= 92.35 grams and...
