The main purpose for the use of Apollo Valves is to protect water users, and extend energy efficiency. Energy efficiency is a huge part of today's world, because it helps the environment, and saves money.
How did Apollo use/work the Lyre...... how are different sounds produced.? How did Apollo use/work the Lyre...... how are different sounds produced.?
Most use valves, but a slide version does exist.
The use of the valves in the heart is to have blood flow regularly through the heart. The valves pump blood out of the heart into the body.
Yes the Apollo 11 astronauts did use the L.E.M or the Lunar Explorer Module.
Apollo 13 did not use a Space Shuttle. Apollo 13 was in April, 1970. The Space Shuttle was not invented until the '80s. Apollo 13 was launched by Saturn V.
French horns do have valves, but not the same kind trumpets use. Trumpets use pistons, and french horns use Rotary Valves. However, a marching french horn, a melophone, does have piston valves.
No, the Apollo Program was cancelled after the final moon landing (Apollo 17) in December 1972.
yes
No, you cannot use Presta valves in Schrader rims as they are not compatible due to differences in size and design.
Apollo was an archer, so he used the bow and arrow.
The Apollo 13 crew DID shut down the reactant valves when ordered to by mission control. They were asked to shut down the Oxygen reactant valves to two of the three fuel cell in a vain effort to stop the venting of the oxygen into space. The reason there was a slight reluctance for mission control to order the valve shutdown, is that once closed, these valves cannot be re-opened and the two fuel cellls would then become unusable. Mission rules state that there must be at least two fully functioning fuel cells before a landing can be attempted. shutting down the two reactant valves effectively aborted the landing mission. However the true damage to the spacecraft was so severe that this was a moot point anyway, and the landing would have to have been aborted in any case.
No, Presta valves are not compatible with Schrader rims. Presta valves are thinner and require a smaller hole in the rim, while Schrader rims are designed for the wider Schrader valves.
