A dog food manufacturer wishes to carry out the canning and sterilization process of a new pet food product at 100.°C, 0.0100 MPa. After crawling around in the rafters of the plant, an engineer finds a 1.60 MPa wet steam line. A pipe is run from this line to the canning area, where it produces 1.40 MPa steam with 2.00% moisture.
Now, instead of just throttling down to the 0.0100 MPa state needed and wasting all that energy, the engineer decides to drop the pressure through a small adiabatic steam turbine.
a. What steam mass flow rate must be used to obtain 1.00 hp from the turbine?
b. What is the turbine's entropy production rate under these conditions?
