Railway tracks made of 1025 Steel are to be laid at a time of year whenthe temperature averages 4 °C. If a joint space of 5.4 mm is allowedbetween the standard 11.9 m length, what is the hottest temperature thatcan be tolerated without the introduction of thermal stresses? Take thecoefficient of linear expansivity of the steel as 12 x 10-6 K-1.

Thick fluids such as asphalt and waxes and thepipes in which they flow are often heated in order to reducethe viscosity of the fluids and thus to reduce the pumpingcosts. Consider the flow of such a fluid through a100-m-long pipe of outer diameter 30 cm in calm ambientair at 0°C. The pipe is heated electrically, and a thermostatkeeps the outer surface temperature of the pipe constant at25°C. The emissivity of the outer surface of the pipe is 0.8,and the effective sky temperature is -30°C. Determine thepower rating of the electric resistance heater, in kW, thatneeds to be used. Also, determine the cost of electricityassociated with heating the pipe during a 10-h period underthe above conditions if the price of electricity is $0.09/kWh.
