Through a clerical error, our purchasing department ordered a finely crafted but mysterious device from a foreign manufacturer (Figure 9.30). The manuals are all in a foreign language, and the only intelligible information is in the form of some numbers printed next to the entrance and exit ports and the rotating shaft.

The 10.0 kW rating on the shaft may mean either a work input or a work output. Determine

a. The flow direction, a to b or b to a.

b. The mass flow rate.

c. The entropy production rate of the device.

Assume a steady state, adiabatic device and that the working substance is H2O. Assume also that the kinetic and potential energies of outlet and inlet flow streams are negligible.
