A steam turbine takes vapor at 463 deg c and exahusts it to a steam boiler at 238 deg c. the turbine then recieves a steam from the boiler at this temperature and exhausts it to a condenser at 38 deg c. what the is the maxumim efficiency of this combination.
honestly, i am not sure what equation to use. i tried efficiency=work/Q but then i have unknown variables.
The Attempt at a Solution
(under relevant equations) all i am sure of s that i have to convert to kelvin, which makes the new temperatures 736, 511, and 311 respectivley.
