WebDec 17, 2014 · In an accretion disk, viscosity causes each ring of gas to spiral inward toward the hole with a radial speed $ u^r \ll\text{(orbital velocity)} = (M/r)^{1/2}$. If this were the only effect of viscosity, the warping of the disk would consist of a differential precession.

Therefore, the accretion e ciency for black holes can in principle be the highest accretion e ciencies in astrophysics. Unlike stars, for black holes all the emitted energy must come from the accretion disk. dennis rader and his family

As the gas speeds up, it transitions from sub to supersonic flow. Much as with the Concorde, this transition can lead to transonic shocks, where the gas abruptly slows down as it piles into itself. dennis rader case summary
