An aluminum pipe has a length of 69 m at a temperature of 8°C. An adjacent steel pipe at the same temperature is 5 mm longer. At what temperature will the aluminum pipe be 15 mm longer than the steel pipe? Assume that the coefficient of thermal expansion for the aluminum is 22.5×10-6/°C and that the coefficient of thermal expansion for the steel is 12.5×10-6/°C.

Wet coal is dried in a continuous rotary dryer that operates at atmospheric pressure. The chips with a water content of 40 wt% and must leave with a moisture content of less than 15%. Hot air is fed to the dryer at a rate of 11.6 m (STP)/kg wet coal. HOT AIR MOIST AIR DRYER WET COAL DRIED COAL To monitor the performance of the dryer by sampling the exiting coal and determining their moisture content directly would be a cumbersome procedure and almost impossible to automate. Instead, wet- and dry-bulb thermometers are mounted in both the inlet and outlet air lines, and the moisture content of the exiting chips is determined by a material balance calculator. (STP: Standard Temperature and Pressure is 0*C and 101.325 kPa) (a) The hot air stream has an absolute humidity of 0.058 kg moisture/kg dry air and leaves with 0.087 kg moisture/kg dry air, calculate the mass of water in the exiting air per kilogram of wet coal fed. (b) Can the dryer reduce the wet coal moisture to 15%? If the answer…
