<div>Hello,</div><div> </div><div>Does anyone knows how to convert a quadratic efficiency equation (eta=a0-a1*(DT/I)-a2*DT^2/I with DT=0.5*(Tfluid_outlet-Tfluid_inlet)-Tamb) of a parabolic trough collector to a linear efficiency equation (eta=a-b*DT/I)? I need this conversion in order to use Type 536.</div>
