Figure 6.2:Flow streams entering and leaving the volume element. We also can express the volumetric owrate as a mass owrate divided by the density, Q = m = W _ f = m 0 P 0 0 m 1 P 1 1 The overall rate of work can then be expressed as W _ = W _ f + W _ s + W _ b = m 0 P 0 0 m 1 P 1 1 + W _ s + W _ b (6.4) 4/149
