In the engr 10 lab (e391), there are 50 long light bulbs (p=100 w) and 30 regular bulbs (p=60 w). how much energy is consumed lighting the lab during the 3 hour lab period. calculate the amount of energy saved if all bulbs are replaced by cfl (spiral) bulbs (p=25w). b) calculate the amount of natural gas (ft3) needed to provide the energy to keep the lights (long + regular) in the e391 lab on overnight for a month (10 hours per day for 30 days)? in other words how much extra energy ( cubic feet of natural gas) have to purchase when we don't turn off the light in lab explain and show formula

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.
