Can we build a pipe to space?

Can we build a pipe to space?

So, to the question. If you run a pipe from Houston into space—nothing will happen. The 60 mile deep column of air inside the pipe will just sit there, pulled down by gravity, just like all the air around the pipe.

Can we pump water into space?

No. The energy consumed and waste heat produced by the act of pumping the water to such a height would outweigh the heat removed by the ice upon its return. The water would also acquire quite a bit of kinetic energy during its descent and that energy has to go somewhere.

Why doesn’t the vacuum of space destroy the atmosphere?

Magnetic fields also help keep atoms close by. The orbit of the moon pulls on the earth which gives it a more powerful magnetic field than other planets. This prevents the atmosphere from being stripped away by radiations from the sun.

Why space elevators are impossible?

The biggest challenge of building a space elevator may be the 100,000-kilometer-long tether. It would have to be incredibly strong to handle the gravitational and centrifugal forces pulling on it. The steel used in tall buildings wouldn’t work for a space elevator cable.

Can we eject CO2 into space?

The CO2 breathed by astronauts aboard the ISS is captured by using a sponge-like mineral called a zeolite, which has tiny pores to lock in a CO2 molecule. On the space station, the zeolites empty their CO2 when exposed to the vacuum of space.

Can we get rid of ocean water?

There are several ways to remove salt from water. Reverse osmosis and distillation are the most common ways to desalinate water. Reverse osmosis water treatment pushes water through small filters leaving salt behind. Distillation on a large scale involves boiling water and collecting water vapor during the process.

Would a body decompose in space?

If you do die in space, your body will not decompose in the normal way, since there is no oxygen. If you were near a source of heat, your body would mummify; if you were not, it would freeze. If your body was sealed in a space suit, it would decompose, but only for as long as the oxygen lasted.

Why does your blood boil in space?

In space, there is no pressure. So the boiling point could easily drop to your body temperature. That means your saliva would boil off your tongue and the liquids in your blood would start to boil. All that bubbly boiling blood could block blood flow to vital organs.

Has anyone been lost in space?

A total of 18 people have lost their lives either while in space or in preparation for a space mission, in four separate incidents. Given the risks involved in space flight, this number is surprisingly low. The remaining four fatalities during spaceflight were all cosmonauts from the Soviet Union.

Is anyone building a space elevator?

NASA says the basic concept of a space elevator is sound, and researchers around the world are optimistic that one can be built. The Obayashi Corp., a global construction firm based in Tokyo, has said it will build one by 2050, and China wants to build one as soon as 2045.

What does the Sabatier system do?

The Sabatier process uses a nickel catalyst to interact with hydrogen and carbon dioxide at elevated temperatures and pressures to produce water and methane. The water is retained for recycling processes, and the methane is vented outside of the space station.

Would water be sucked into space if it was stuck?

No the water would not be sucked into space. It’s true that one end would be open to space and so there would be no air pressure on that end. So water would rise in the tube. But as the water rises, the weight of the water in the tube would increase.

How much water is transferred between two reservoirs through a pipeline?

A uniform pipeline, 5000m long, 200mm in diameter and roughness size of 0.03mm, conveys water at 20℃ (ν=1.003×10−6 m2/s)between two reservoirs as shown in the figure. The difference in water level between the reservoirs is 50m. Include all minor losses in your calculations, determine the discharge.

What stops water from boiling when it boils in space?

The water in the tube that is open to space will have no air pressure on it, so it will boil, even though it is only 34 feet high. As it boils away the vapor pressure on the water (caused by gravity pulling the water vapor down) will eventually stop it from boiling.

What are the horizontal forces on water in a pipe?

For a flowing liquid, water in general, through a pipe, the horizontal forces on water between two sections (1) and (2) are: P1 A = P2 A + FR P1= Pressure intensity at (1). = Cross sectional area of pipe.
