Fluid flow and momentum equation. Do I have the right equation?

    F1x+F3x = density x Q(Vx2 – Vx1)
    F1x = -Rx
    F3x= (pressure 1 x area 1) + (Pressure 2 x area 2) (Cos B)
    F1y+F3y = density x Q(Vy2 – Vy1)
    F1y = -Ry
    F3y = (Pressure 2 + Area 2)(Cos B)
    So is it:
    Rx= (pressure 1 x area 1) + (Pressure 2 x area 2) (Cos B) - density x Q(Vx2 – Vx1)
    Ry = (Pressure 2 + Area 2)(Cos B) - density x Q(Vy2 – Vy1)

    You mind defining all your variables just so that we don't make any assumptions about what you mean?
