Question 11. We want to slip an aluminum (a = 24 x 10-6/K) ring over a steel (a = 12 x 10-6/K) bar. At 10°C the inside diameter of the ring is 4.000 cm and the diameter of the rod is 4.040 cm.i) In order for the ring to slip over the bar, should the ring be heated or cooled?ii) Find the temperature of the ring at which it fits over the bar. The bar remains at 10 °C%3Da) neither , 426° Cb) heated , 416° Cc) cooled , 426° CO d) heated , 426° C

2. Compare the heat loss from an insulated and an uninsulated copper pipe (k-400 W/m K) under the following conditions. The pipe has an internal diameter of 10 cm and an external diameter of 12 cm. The inside surface temperature of the pipe is at 110°C. The pipe is located in a space where all possible outside surface temperature of material was maintained at 30°C. The insulation available to reduce heat losses is 5 cm thick and its conductivity is 0.20 W/m K. If the furnace for heating the fluid in the pipe operating at an efficiency of 85% using natural gas priced at Cg = Php 1.00/MJ, what is the daily cost of heat loss per meter of pipe?
