1. A fluid with a density p =1 is contained within the control volume V(t) bounded by the surfaces x=0, x=1, y=0.2t, y= 0.5 (1+t), z=0, z=1. a) First, calculate the total mass of the fluid contained within the control volume by evaluating Sve pav and then determine the time rate of change of total mass within the control volume. b) Evaluate the time rate of change of total mass within the control volume by applying the general transport theorem, i.e., a Sve pdV = Svw dv + Sace) P(w.n) dA Sve) at %3D
