Constants Part A You are asked to design a cylindrical steel rod 60.0 cm long, with a circular cross section, that will conduct 180.0 J/s from a furnace at 400.0 ° C to a container of boiling water under 1 atmosphere. What must the rod's diameter be? Express your answer with the appropriate units. D. Vale Unis D- Value Units
A cylindrical rod of 1040 steel having originally 11.4 mm in diameter is cold-worked by drawing (i.e. pulling through a die with a hole smaller than the original rod cross section). The circular cross section will be maintained during deformation. The deformed steel is desired to have tensile strength in excess of 825 MPa and ductility of at least 12% EL. The final diameter must be 8.9 mm. Explain how this may be accomplished.
One end of a long rod 3 cm in diameter is inserted into a furnace with the (3 outer end projecting into the outside air. Once the steady state is reached the temperature of the rod is measured at two points, 15 cm apart and found to be 140°C and 100°C, when the atmospheric air is at 30°C with convection coefficient of 20 W/m2.K. Calculate the thermal conductivity of *.the rod material Consider a stainless steel spoon(k = 15.1 W/m.K), partially...
