The amount of solar energy absorbed = Change in enthalpy of air + Heat losses to the Surroundings + Frictional energy loss + change in pressure energy + change in potential energy + change in kinetic energy. A case study with solar collector area equal to the collector area of the Manzanares prototype was used to run the mathematical model. it was solved by the best fit method starting with a simplified base case, where all the above losses factors are treated as negligible to obtain expressions for rise in temperature, velocity of emerging air draft
and hence its kinetic power. Subsequently, all the above factors are included one by one to obtain similar expressions. Based on these results, the author discussed the effect of heat losses, lapse rate, frictional pressure drop and ambient wind velocity on the power output [10].
