An electric current of 1 A passing through a cable has a measured voltage of 30 V across the cable. The cable is covered with polyethylene insulation, and convection occurs at the outer surface of the insulation. The ambient temperature is 20°C with a convection heat transfer coefficient of 5 W/m2•K, and the surface area subjected to the convection is 0.1 m2. The ASTM D1351 standard specifies that thermoplastic polyethylene insulation is suitable for use on electrical cable with operation at temperatures up to 75°C. Under these conditions, will the polyethylene insulation for the cable meet the ASTM D1351 standard? If the polyethylene insulation does not meet the ASTM D1351 standard, then discuss possible solutions to meet the standard.

A circular copper tube with an inner diameter of 2 cm and a length of 100 m is used to transport drinking water. Water flows in the tube at an average velocity of 0.11 m/s at 20°C. At the inner tube surface, the mass concentration of copper in water is 50 g/m3. The Environmental Protection Agency (EPA) sets the standards for the National Primary Drinking Water Regulations (NPDWR) that apply to public water systems. The drinking water regulations limit the levels of contaminants in drinking water to protect public health. The maximum contaminant level for copper in drinking water, set by the NPDWR, is 1.3 mg/L. Above that, additional steps are required to treat the water before it is considered safe for the public. Determine whether the water from the tube has a safe level of copper as

per the NPDWR. The diffusion coefficient for copper in water is 1.5 × 10?9 m2/s. What will be an ideal response?
