Use PVWatts to simulate a PV system in Wichita that uses 8 Mitsubishi PV-MLU255HC panels and an Outback Sealed GTFX2524 inverter. The panels are oriented due south with a tilt of 37 degrees. a. Print the PVWatts output page. b. Plot the output for March 21, June 21, September 21, and December 21. Discuss differences in the four plots. .

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false

Awall of 0.5m thickness is to be constructed from a material which has average thermal conductivity of 1.4 w/mk. the wall is to be insulated with a material having an average thermal conductivity of 0.35 w/mk so that heat loss per square meter shall not exceed 1450 w. assume inner wall surface temperature of 1200°c and outer surface temperature of the insulation to be 15°c. calculate the thickness of insulation required.

Apressure vessel with an r/t 20 cannot be treated as thin walled vessel. a)-trune b)- false
