The weight of the mass added to the hanger is equal to the extra force on the gas, but what area should we use to calculate the added pressure from this mass?

with some of the experimental details out of the way, let's think a bit about what we expect to see in our data if the ideal gas law is a good model for our gas. we would like to verify the ideal gas law pv = nrt

Asteel tube (k=50 w/mk) of inner and outer diameter di = 20mm and do=26mm, respectively, is used to transfer heat from hot gases flowing over the tube (h-hot = 200w/m2k) to cold water flowing through the tube (h-cold = 8000 w/m2k). what is the cold-side overall heat transfer coefficient uc? to enhance heat transfer 16 straight fins of rectangular profile are installed longitudinally along the outer surface of the tube. the fins are equally spaced around the circumference of the tube, each having a thickness of 2mm and a length of 15mm. what is the corresponding overall heat transfer coefficient uc? *solve for uc in both cases*
