Why do astronauts need an air tank?
Astronauts need an air tank to supply them with oxygen to breathe in the airless environment of space, where there is no atmospheric pressure to support life. The air tank also helps regulate the pressure inside the astronaut's suit and provides a way to expel carbon dioxide.
What caused the master alarm to go off in Apollo 13?
The master alarm in Apollo 13 was triggered by the high oxygen tank pressure caused by a damaged Teflon insulation on the wires inside the tank. This led to a series of malfunctions and a subsequent explosion in the oxygen tank.
How much is a oxygen tank?
The cost of an oxygen tank can vary depending on the size, type, and supplier. On average, a small portable tank can cost between $50 to $200, while larger tanks for home use can cost several hundred dollars. Additionally, there may be additional costs for refills or rental fees.
What happens to and where does the external fuel tank go after a shuttle takes off?
The external tank is jettisoned from the Orbiter less than a minute after main engine cut off (MECO which occurs about eight minutes after launch). The tank does not enter or leave Earth orbit. It is maneuvered such that it's trajectory will take it to an unoccupied area of either the Pacific or Indian Oceans (depending upon the launch profile). The tank is made to roll end over end as it descends so that it increases the atmospheric friction and causes it to disintegrate prior to making contact with the ocean. Nasa does warn inhabitants in the affected areas in case some debris does reach the Earth's surface.
What would make you explode in space?
Internal fuel tank explosion, as in the case of Apollo 13. Heat applied to the fuel tank as in the case of Challenger, or heat from reentry in the Earth's atmosphere as in the case of Columbia. Being hit by a meteor, asteroid, comet, or space junk that previous space missions have left in orbit. There could be land to space ASAT (anti satellite) missile, as in Feb. 2008, when the USS Lake Erie (in the Pacific Ocean) launched a missile and blew up a out of control USA satellite.
How many liters of air are in a scuba tank at atmospheric pressure?
A scuba tank typically holds about 11 liters of air at atmospheric pressure.
If 3750 liter of air must be compressed into a 26 liter tank what will be the final pressure of the air in the tank?
assume that the air is originally at atmospheric pressure
Does atmospheric pressure have any effect on the oxygen level in the scuba tank?
No, only when it is released into the atmosphere at the ambient pressure.
How much electricity required to develop 1 bar pressure in a compressor?
None! A tank at atmospheric pressure already has an absolute pressure of 1.013 bar.
What are the difference between room pressure and absolete pressure?
Room pressure refers to the pressure within a confined space like a room, which may be controlled to prevent contamination or maintain a sterile environment. Absolute pressure, on the other hand, refers to the total pressure within a system including both atmospheric pressure and any additional pressure exerted.
What is the difference between a tank and vessel?
A tank is designed to hold the maximum hydrostatic pressure at the base -- based on the depth of the tank, the density of the material it holds, and maximum atmospheric pressure (with added margin for safety). A tank wall may be constructed with 'thicker' material at the base and 'thinner' material at the top, to save cost. The top of the tank need only support its own weight (plus safety margin). A pressure vessel must withstand the rated pressure at all points around the surface of the vessel.
What is the relationship between the water pressure, tank air pressure, and the overall performance of a water pressure tank system?
The water pressure in a tank system is directly related to the tank air pressure. The tank air pressure helps regulate the water pressure and overall performance of the system. If the tank air pressure is too low, the water pressure may drop, affecting the system's efficiency. Conversely, if the tank air pressure is too high, it can cause the water pressure to be too high, potentially damaging the system. Maintaining the correct balance between water pressure and tank air pressure is crucial for optimal performance of the water pressure tank system.
What is the relationship between air pressure and a water tank?
The relationship between air pressure and a water tank is that the air pressure in the tank affects the flow and pressure of the water coming out of it. The air pressure in the tank helps to push the water out when a faucet is opened, creating a steady flow of water. If the air pressure in the tank is too low, the water flow may be weak or inconsistent.
What is the relationship between propane tank pressure and temperature?
The relationship between propane tank pressure and temperature is direct. As temperature increases, the pressure inside the tank also increases. Conversely, as temperature decreases, the pressure inside the tank decreases. This is due to the fact that propane is a gas and its molecules move more rapidly at higher temperatures, exerting more pressure on the walls of the tank.
What is the recommended pressure level for a pressure tank?
The recommended pressure level for a pressure tank is typically between 40 to 60 pounds per square inch (psi).
What is the recommended pressure setting for a pressure tank?
The recommended pressure setting for a pressure tank is typically between 40 to 60 pounds per square inch (psi).
Could the hot water tank be causing the water pump to be losing pressure?
No. Nothing to do with it. Much more likely there is an air leak between pump and pressure tank, or pressure tank needs a new aircharge.
