Water is boiled at 3344 kPa with a stainless steel plate. The stainless steel plate is circular with a diameter of 50 cm, and its surface is mechanically polished. The ASME Boiler and limits the maximum use temperature for ASME SA-240 stainless steel plate to 260°C. Determine whether the stainless steel plate complies with the ASME Boiler and Pressure Vessel Code if it is used to boil the water at an evaporation rate of 4 kg/s. Assume nucleate boiling. Is this a good assumption? Use the property tables to calculate the properties of water at saturation temperature. The surface tension σ at 240°C is 0.0284 N/m. Also, Csf = 0.0130 and n = 1.0 for the boiling water on a mechanically polished stainless steel surface.
