A proposed ocean power plant will utilize the temperature difference between surface seawater and seawater at a depth of 100 meters. Assume the surface temperature is 25° Celsius and the temperature at the 100-meter depth is 3° Celsius. 1. What is the ideal (Carnot) efficiency of the plant? 2. If the plant generates useful energy at the rate of 100 megawatts while operating with the efficiency found in part (a), at what rate is heat given off to the surroundings?...
Chapter 13, Problem 01 The amount of heat per second conducted from the blood capillaries beneath the skin to the surface is 280 J/s. The energy is transferred a distance of 2.1 × 10-3 m through a body whose surface area is 1.8 m2. Assuming that the thermal conductivity is that of body fat, determine the temperature difference between the capillaries and the surface of the skin. Chapter 13, Problem 02 In an electrically heated home, the temperature of the...

Heat Conduction Heat conduction occurs through any material, represented here by a rectangular bar, whether window glass or walrus blubber. The temperature of the material is T2 on the left and T1 on the right, where T2 is greater than T1. The rate of heat transfer by conduction is directly proportional to the surface area A, the temperature difference T2 - T1, and the substance's conductivity k. The rate of heat transfer is inversely proportional to the...
