You need to prepare to perform a First Law analysis on a device. Upon inspection, you see that the device is small, uninsulated, has one inlet and one outlet, and has no obvious work inputs or outputs. The operator tells you that steam enters through the inlet and liquid water exits through the outlet. The operator says that he turns it on at the beginning of the day, and turns it off at the end, and never has to pay any attention to its operation. Beginning with the general equation for the First Law of Thermodynamics, develop a simplified expression that should be suitable for use with this device.
