NCER Tutorial No.-2 1.To difine the following terms and difference btw their meaning- a. Direct radiation, diffuse radiation and global radiation b. Azimeth angle, zenith angle and inclination angle c. Local apprant time, local clock time and global mean time 2. Find the hour angle at sun rise and sun set 22 march for his surface at inclination angle 20° facing south woards at Moradabad. 3. Discuss the parameters gouerning performing the flat plat collectors. 4. In a glazed FPC only a fraction of α of radiation is absorb and the rest is reflected. In a multiple counter system with a (ρ) as the Reflectance for diffuse light then prove that the (Ʈα)ᵑᵉᵗ= Ʈα/[1-(1-α)ρα] (α in suffix) 5. For a CPC the angle of acceptance 20°, the width of the absorbed in 10cm and the absorber tube outer dia 6cm. Calculate the C.R.(concentrtion ratio.) 6.Write the short notes on following- a. Solar thermal storage system b. Solar water heating system c. Solar ponds and destillation system d. Solar air heating system e. Solar cooking system f. Solar RAC system g. Solar photovoltic system 7. What are the different thermo dynamic cycle and how their use fuel solar power plant ? 8. Explain different active and passive solar heating system ? 9.
