H2o (pc model) is steadily flowing through an insulated 20-cm diameter tube with a mass flow rate of 1 kg/s and is electrically heated from 100 kpa, 100 deg-c at the inlet to 500 deg-c at the exit.
you can use suitable testapps for solving this problem:

a. determine the ratio of exit velocity to inlet velocity.

b. the electrical power input (in kw) if ke is not neglected

c. if ke is neglected, by what percent will the answer in part (b) change?

d. determine the rate of entropy generation.
