Solar Panel Repair
How much oxygen will be needed to accomplish this?
Each EMU has oxygen tanks (similar to scuba diving tanks) that work with a carbon dioxide removal system to allow a 6- to 8.5-hour spacewalk. Without the ability to remove carbon dioxide, the oxygen in the tanks would run out more quickly, because much would be tied up in exhaled gas. The amount of oxygen consumed, and carbon dioxide produced by a crewmember is dependent on his/her metabolic rate. (The life support system holds other things that get consumed during a spacewalk as well, including a battery and cooling water.) The suit contains .54 kilograms of oxygen (at a pressure of 5,860.5kilopascals) for one EVA lasting between 6- and 8.5-hours.
the question is :
Two station astronauts will need to perform five 6-hour EVAs within 14 days to repair a damaged Solar Panel that was impacted by a micrometeoroid on the space station.
i need to learn how to solve this equation
please help
What equation?
EDIT:
Design is an inexact art. As you said, each EMU O2 tanks allow 6-8.5 hours of spacewalk and two astronauts have to perform five 5-hours spacewalk, so, a total of 2*5*6 = 60 hours of spacewalk has to be performed.
As metabolic rates of astronaut is not given in the problem(), I am going to calculate the minimum and maximum amount of oxygen required.
Minimum = 60/6 = 10 units of EVA = 10*0.54 =5.4Kg at 5860 KPa pressure.
Maximum = 60/8.5 = 7.06 units of EVA = 8 Units(to be on safer side) = .54*8 = 4.32 Kg of O2 at 5 860 KPa.
This is all, what I can conclude form the things you provided above.
