When the question is about “how many 12 AWG in PVC 40,” it seems to refer to the number of 12-gauge (AWG) wires that can be safely placed inside a conduit made from PVC with a schedule 40 rating. The precise number depends on the conduit's diameter. For scheduling purposes, the National Electrical Code (NEC) Table C.9 or the applicable code should be referenced, as it gives guidelines for conduit fill capacities. For example, a 1/2 inch Schedule 40 PVC conduit can typically accommodate five 12 AWG wires, but this can vary based on factors like the wire insulation type and whether the wires are power or control cables. For an accurate count and to ensure compliance with local regulations, consulting the NEC or a professional electrician is recommended.

Emulsion cooking refers to the process of combining two ingredients that usually do not mix together, such as oil and water, to create a stable blend. Emulsions in cooking serve as the base for many sauces and dressings, such as mayonnaise, hollandaise, and vinaigrettes. The process often involves slow addition and vigorous mixing of one ingredient into another, typically incorporating an emulsifier like egg yolks or mustard to help stabilize the mixture. Emulsion cooking is crucial for achieving the desired consistency and flavor profile in various dishes. Mastery of this technique can enhance the texture and coherence of culinary creations, making it a fundamental skill in both professional kitchens and home cooking.

The rate at which ink on a cardboard box fades is influenced by several factors, including the quality of the ink used, the type of cardboard, exposure to light, environmental conditions, and handling. Typically, UV exposure accelerates fading, with direct sunlight being particularly detrimental. Inks that are UV resistant tend to last longer. However, under standard storage conditions—away from direct sunlight and in a dry environment—ink on cardboard can remain legible for years. Cheap inks or exposure to harsh conditions can lead to quicker fading, sometimes within months. To preserve the legibility and appearance of printed cardboard boxes, it is advisable to store them away from direct sunlight and in stable, moderate humidity conditions.
