Liquid water at 100 kPa, 30oC enters a boiler through a 2 cm-diameter pipe with a mass

Question:

Liquid water at 100 kPa, 30oC enters a boiler through a 2 cm-diameter pipe with a mass flow rate of 1 kg/s. It leaves the boiler as saturated vapor through a 20 cm-diameter pipe without any significant pressure loss. Determine
(a) The exit velocity (V2), the rate of transport of energy at
(b) The inlet.
(c) Exit. Neglect potential energy, but not kinetic energy.
(d) What-if Scenario: What would the rate of transport of energy at (d) inlet.
(e) Exit be if kinetic energy were neglected?
