(25 pts) Estimate how much collector area and storage capacity would be required for an active solar hot-water system designed to supply the total needs for two four-person families, one living in Manchester, New Hampshire, where the latitude is 44+o north and the other in Albuquerque, New Mexico, at 35+o North. The heat capacity of water is about 4200 J/kgoC and the hot water supply temperature in both houses is 60oC (140oF). State and justify all additional assumptions made.

The brightest star in the night sky in the northern hemisphere is sirius. its distance from earth is estimated to be 8.7 light years. a light year is the distance light travels in one year. light travels at a speed of 3.00 × 108 m/s. calculate the distance from earth to sirius in miles. (1 mi = 5280 ft) g
