Define efficiency W/Qh = 0.5ln2/(ln2+0.75) = 0.24015.
Algebra error.
The denominator is Qh, which is just ln(2),
not ln(2) + 0.75.
I have no idea where that 0.75 came from.
I get efficiency of 0.5, as expected.
Hint: I used a spreadsheet to run an example.
That makes it particularly easy to check the work.
