As your error states, you have a unit unbalance.  If you make the second term unitless the problem will solve:

Note that the units chosen may affect the result.

That will not work lake that.

You are subtracting a number with units (the expression involving the square root) from a number without units. That makes no sense.

Figure out the meaning of 1.15 and 5.75, or if you need to supply Hs and Tp without units.

 

Success!
