ME 440-01 Heat Transfer\ Spring 2024\ Homework 1\ Instructor: Bikram Bhatia\ Assigned: January 15, 2024 | Due: via Blackboard, at 2:50 pm on Monday, January 22, 2024\ Problem 1. The concrete slab of a basement is

11m

long,

8m

wide, and

0.20m

thick. During the winter, temperatures are nominally

17\\\\deg C

at the top and

10\\\\deg C

bottom surfaces, respectively. If the concrete has a thermal conductivity of

1.4(W)/(m)*K

, what is the rate of heat loss through the slab? If the basement is heated by a gas furnace operating at an efficiency of

\\\\eta _(f)=0.90

and natural gas is priced at

C_(g)=$(0.02)/(M)J

, what is the daily cost of the heat loss?

If the concrete has a thermal conductivity of 1.4W/mK, what is the rate of heat loss through the slab? If the basement is heated by a gas furnace operating at an efficiency of f=0.90 and natural gas is priced at Cg=$0.02/MJ, what is the daily cost of the heat loss?
