There is a steady isothermal flow of water at 20°C through the device in the figure given below. Heat- transfer, gravity, and temperature effects are negligible. Known data are D? = 9 cm, Q? = 235 m³/h, p1 = 150 kPa, D2 = 7 cm, Q2 = 100 m³/h, p2 = 225 kPa, D3 = 4 cm, and p3= 265 kPa. 3 Isothermal steady flow Calculate the rate of shaft work done for this device.
