Okay, I'm new to this but I meant to say ##\int ##\rho## dv## + ##\int ##\rho## V dA##
I can't quite get the syntax down. But its the integral with respect to the control volume of the density * the dv (volume) + the integral with respect to the surface area of the density * the volume * dA (Area)
Homework Statement
A tank of constant volume V contains air at an initial density pi. Air is discharged isothermally from the tank at a constant volumetric rate of Q (with SI units of m^3/s). Assuming that the discharged air has the same density as that of the air in the tank, find an...
