First, figure A-1 shows a simple drawing for the project (The performance of the solar collector) that include the stainless-steel pipe and reflector surface. second, it shows the flowing steps for the project and how the project works which is staring from seawater going through the pip that can heat seawater  using solar energy by pump. Third, figure A-2 shows how much amount of power could have from reflector surface which is 203 W by using the power formal. This was starting by determined the size of the reflector surface which is 50 X 24 inches to give how much amount of power could have. Fourth, figure A-3 shows the length of the stainless tube 54 inches with outside diameter 1” and inside diameter 0.902” and wall thinness 0.049”. Fifth, figure A-5 shows how much amount of clear water could have by using the fluid formal which is 36 ml/min. Sixth, Figure A-6 to A-8 shows the parabola calculation and the calculation, it could find curve for the parabola. What is parabola?  Parabola mathematical is analysis of the cut surface shows a distinct property every point on a parabolic curve is equal a point and a line between each other. X2 =4ay the formal was using to determent the focus point. The focus point was 6. Seventh, Figure A-9 shows the calculations from the equations Re = ρvD/μ and mdot=ρvA for the Reynolds number of the seawater in the collector pipe. The Reynolds number of 570 signifies laminar flow. In this way, some type of static blender was using to mix the water. Eighth, Figure A-10 shows the calculations of the velocity of the water in the solar collector. As shown, the water velocity 1.25 cm/s.
