Steam flows steadily through a single-flow device with a flow rate of 10 kg/s. It enters with an enthalpy of 3698 kJ/kg and a velocity of 30 m/s. At the exit, the corresponding values are 3368 kJ/kg and 20 m/s respectively. If the rate of heat loss from the device is measured as 100 kW,
(a) Determine the rate of work transfer. Neglect any change in potential energy.
(b) What-if Scenario: What would the rate of work transfer be if the change in kinetic energy were also neglected?
