An incompressible liquid is gushing out of a thin pipe deep in the middle of an ocean with the rate of q cubic meters per second. assuming radially-symmetric flow around the pipe (that is, ignoring the momentum of the liquid as it comes out of the pipe), derive the expression for velocity distribution as a function of the distance r to the center. (b) use the bernoulli's law to find the hydrostatic pressure p as a function of the distance r and relative height ah.
