Question

Analytical Steps mostly

Create two sets of plots (one set for Evansville and one set for Phoenix, AZ) that show how the following factors impact the exit temperature for the solar collector. The initial temperature of the water is 22°C. Assume a constant heat removal factor of 0.95, and a glass cover with a transmissivity of 0.97. Unless otherwise stated, use values from Part 1 for remaining variables. Vary absorber plate surface properties:

• Black nickel oxide plated metal ? = 0.92

• Black chrome plated metal ? = 0.87

• Galvanized sheet metal ? = 0.65
