I'here is a steady isothermal flow of water at 20°C through
the device in Fig. P3.165. Heat-transfer, gravity, and tem-
perature effects are negligible. Known data are D, = 9 cm,
Q1 = 220 m/h, p1 = 150 kPa, Dz = 7 cm, Q2 = 100 m³/h,
P2 = 225 kPa, D3 = 4 cm, and p3 = 265 kPa. Compute the
rate of shaft work done for this device and its direction.
