For an inviscid fluid we have euler's equation (vectors are denoted by bold characters) )= vp - vgx + v xu at and whether or not the fluid is incompressible, we also have the conservation of mass dp +pv u 0. dt show that x vp dt deduce that, if p is a function of palone, the vorticity equation is exactly as in the incompressible, constant density case, except that ois replaced by ap.

as a general rule, scissors have blades less than 6 in (15 cm) long and usually have handles with finger holes of the same size. shears have blades scissors used to cut hair or fabric must be much sharper.
