Question

A steam turbine has steam flowing at steady rate of 5 kg/s entering at 5 MPa and 500oC and leaving at 0.2 MPa and 140oC. During flow through turbine a heat loss of 600 kJ/s occurs to the environment at 1 atm and 25oC. Determine (i) the turbine output (ii) the irreversibility Neglect the changes in kinetic energy and potential energy during flow.

Answer 1

Explanation:

(i) the turbine output

(ii) the irreversibility Neglect the changes in kinetic energy and potential energy during flow.

• rate of 5 kg/s entering at 5 MPa and 500oC and leaving at 0.2 MPa and 140oC. During flow through turbine a heat loss of 600 kJ/s occurs to the environment at 1 atm and 25oC
