Water flows steadily down an insulated vertical pipe (of constant diameter). The following conditions are given at the inlet and exit. Inlet (state-1): T1 = 20 oC, V1 = 10 m/s, z1 = 10 m; Exit (state-2): T(a) The velocity at the exit (m/s).
(b) The pressure at the inlet (in kPa). Use the SL model for water. Do not neglect ke and pe. What-if Scenario: What would be the answer in part c if the change in potential energy was neglected?
