A voltmeter with internal wiring and connection lugs made of copper measures 3.174 mV in the thermocouple circuit below using Iron (Fe), Copper (Cu) and Constantan (C) metals. What is the temperature T1? Use the tables attached to the end of this homework. Please show all your work including "adding zero" to reference temperatures to 0°C, and the law of intermediate metals.

Air at a pressure of 1atm and a temperature of 40 c is in parallel flow over the top surface of a flat plate that is heated to a uniform temperature of 120 c. the plate has a length of 0.40m (in the flow direction) and a width of 0.15m. the reynolds number based on the plate length is 50, 000. what is the rate of heat transfer from the plate to the air? if the free stream velocity of the air is doubled and the pressure is increased to 10 atm what is the rate of heat transfer?
