As part of a heat treatment process, cylindrical, 304 stainless steel rods of 100-mm diameter are cooled from an initial temperature of 500ºC by suspending them in an oil bath at 25ºC. If a convection coefficient of 500 W/m2·K is maintained by circulation of the oil, how long does it take for the centerline of a rod to reach a temperature of 52ºC, at which point it is withdrawn from the bath? If 9 rods of length 1 m are...

As part of a heat treatment process, cylindrical, 304 stainless steel rods of 100 mm diameter are cooled from an initial temperature of 500°C by suspending them in an oil bath at 30°C. If a convection coefficient of 500 W/m2K is maintained by circulation of the oil, how long does it take for the centerline of a rod to reach a temperature of 50°C, at which point it is withdrawn from the bath? If 10 rods of length L =...

You have a nominal 3-inch diameter steel pipe, 15 feet high that is embedded into a concrete foundation. Neglecting the weight of the column, answer the questions below: A. What is the maximum vertical load this pipe can support/critical load (#)? B. If a vertical load of 2,000#s and a horizontal force of 100#s are applied at the top of the column, what are the maximum combined tensile and compressive stresses (psi) where the column meets its foundation? Are they...

Problem 3 (36 Pts) The steel pipe is 0.5 m long and has an internal diameter of 60 mm and an external diameter of 80 mm. The Young’s modulus E is 200 GPa and the Poisson ratio ν is 0.32. The pipe experiences a twisting moment of 8 kNm and a bending moment of 3.5 kNm. 4p a) Sketch roughly how the angle of rotation and vertical displacement change as a function of distance from the free end of the...

In an industrial process, 20 mm diameter spherical steel ball bearings are heat-treated to improve their durability. For application (1), the entire ball bearing needs to be heated evenly to 1000 K. For application (2), only the outer 1 mm of the ball is to be heated to a temperature in excess of 1000 K. The properties of the ball bearing are c = 0.5 kJ/kg*K; p = 7800 kg/m3; k = 50 W/m.K. At your facility, you have access...

Water flows between two reservoirs through 800 ft of 12-inch diameter welded-steel pipe. The water surface elevation difference between the two reservoirs is 16 ft. Find the flowrate (a) assuming head loss is only due to pipe friction, and (b) Accounting for both friction losses and minor losses due to a flush square-edged pipe entrance, the pipe exit, and a half-open gate valve in the line. Assume the water temperature is 60°F.
