Heat treatment of metals is commonly done using electrically heated draw batch furnaces. Consider a furnace that is situated in a room with a surrounding air temperature of 30°C and an average convection heat transfer coefficient of 15?W/m2•K. The outer furnace front surface has an emissivity of 0.7, and the inside surface is subjected to a heat flux of 5?kW/m2. To ensure safety and avoid thermal burns to people working around the furnace, the outer front surface of the furnace should be kept below 50°C. Based on the information given about the furnace, does the furnace front surface require insulation to prevent thermal burns?
Calculate the amount of heat in BTUs required to change the temperature of 10 pounds of copper from 100°F to 150°F. The specific heat of copper is 0.09 BTUs/lb
A) 10 lbs × 50°F = 500 BTUs B) 10 lbs × 0.09 BTUs/lb = 0.9 BTUs C) 10 lbs × 50°F × 0.09 BTUs/lb = 45 BTUs D) The amount of heat required cannot be calculated using the information given.
A diagnostic trouble code (DTC) has been set for a fault with the lateral acceleration sensor or circuit. What test could be performed to check if the sensor is working?
A) Disconnect the sensor and hold it sideways to see if the scan tool reads 0.0 G B) Unplug it and see if the scan tool reads 1.0 G C) Disconnect the sensor and hold it sideways to see if the scan tool reads 1.0 G D) Drive the vehicle in a circle to see if the scan tool reads 0.0 G
