Answer #1

Expansion of Copper tube = L

(L)= (Co-efficient of thermal expansion)*(Change in temperature) *(Length of copper tube)

(L) = (C)*(T) *(L)

But we know that, for Copper, Co-efficient of thermal expansion is C = 9.4 x 10-6 in per in per degree F

T = 600 - 70 = 530 degree F

L = 10 ft = 10 x 12 = 120 inches

(L) = ( 9.4 x 10-6 ) x (530) x (120)

(L) = 0.59784 inches.

Hence, expansion of copper tube = 0.59784 inches.

Problem 8.24 Water is used to cool ethylene glycol in a 60-ft-long double pipe heat exchanger made of 4-std and 2-std (both type M) copper tubing. The water inlet temperature is 60°F and the ethylene glycol inlet temperature is 180°F. The flow rate of the ethylene glycol is 20 lbm/s, while that for the water is 30 lbm/s. Calculate the expected outlet temperature of the ethylene glycol and determine the pressure drop expected for both streams. Assume counterflow, and place...

You have a block of ice at 32 degrees F, and a block of copper at some other temperature. The blocks have equal mass. Exactly the same amount of heat is added to each block. This causes the ice to melt completely, but not to warm up past 32 degrees F. The copper stays well below its melting point. How much does the copper expand? (Express your answer as a percentage, e.g. "the length of the copper increases by 1%.")...
