I used the symbols to write out rho with a subscript...is that what you meant? That is the equation we have to show...so I have no clue how they got it mathematically. For the second your suppose to use the equation of continuity...which I'm not sure which one they mean as I find various...

Homework Statement PARTA: Consider a fluid in which \rho = \rho(x,y,z,t); that is the density varies from point to point and with time. The velocity of this fluid at a point is v= (dx/dt, dy/dt, dz/ dt) Show that dp/dt = \partialt\rho + v \cdot \nabla\rho PARTB: Combine the above...
