Chapter 1 Basics of Heat Transfer 1-37E A copper block and an iron block are dropped into a tank of water. Some heat is lost from the tank to the surroundings during the process. The final equilibrium temperature in the tank is to be determined. Assumptions 1 The water, iron, and copper blocks are incompressible substances with constant specific heats at room temperature. 2 The system is stationary and thus the kinetic and potential energy changes are zero, ΔΔ KE PE == 0 and E U = . Properties The specific heats of water, copper, and the iron at room temperature are C p, water = 1.0 Btu/lbm· ° F, C p, Copper = 0.092 Btu/lbm· ° F, and C p, iron = 0.107 Btu/lbm· ° F (Tables A-3E and A-9E). Analysis We take the entire contents of the tank, water + iron + copper blocks, as the system
