Hello is not a literal song. The million miles she says separates her from the person she's addressing aren't physical â they're emotional. No one who's been through what Adele has could possibly be in the same place psychologically. In four years, she's grown leaps and bounds.
Figure B: Two bathrooms, two roof vents. Each bathroom has its own exhaust fan; each fan vents separately out the roof. If you have two bathrooms that are close together and one has an exhaust fan and the other doesn't, you might be wondering if you can tie a new exhaust duct into the existing one.Well, you can't!ut while you can't have two fans with one vent, you can make one fan and one vent serve two bathrooms. This setup requires an in-line centrifugal fan mounted in the attic drawing air simultaneously from both bathrooms (see photo).
No, it doesn't need any atmosphere to work. The expanding gasses in the exhaust nozzle of a rocket push in all directions at once. Pushing to the sides doesn't do anything, since they push equally on the left and right side, the up and down side. But they also push in the forward and backward directions, too. The gasses that push out the back are gone.
