The ratio for the cross section areas of the
tube is = 0.449, the difference in the
pressures is Pi - P2 = dP = 27.5 Pa, and the
density of the fluid is 1.27 kgm.
Find the speed of the fluid near the right
hand end of the tube (i. e., find v2).
Answer in units of m/s.

Uranium has two naturally occurring isotopes. 238u has a natural abundance of 99.3% and 235u has an abundance of 0.7%. it is the rarer 235u that is needed for nuclear reactors. the isotopes are separated by forming uranium hexafluoride uf6, which is a gas, then allowing it to diffuse through a series of porous membranes. 235uf6 has a slightly larger rms speed than 238uf6 and diffuses slightly faster. many repetitions of this procedure gradually separate the two isotopes. what is the ratio of the rms speed of 235uf6 to that of 238uf6? express your answer to five significant figures.
