basically I am trying to decide if I could use an electric motor as a generator to charge a battery source, and when needed use it as a motor as well. I think the only issue is the rpm's which it is operating at, to get the most efficient electrical generation. Insights would be appreciated.
If your party is anything in between, you may want to go for a half sheet cake. But wait, how big is a half sheet cake? It should be something between a quarter and a full sheet cake, of course. The standard size for most commercial half sheet cakes is 12âx16â. That could feed about 40 to 50 guests, depending on the serving size and on the number of people who would request for second servings.
Below are the dimensions of the two standard US professional quality sheet cake pans used in commercial bakeries. You'll see that even they vary. Full sheet cake = 18 x 24 x 2 inches or 18 x 26 x 2 Quarter sheet cake = 9 x 12 x 2 inches or 9 x 13 x 2 I listed both to point something out to you. A quarter sheet cake is called a quarter because it takes four of them to equal a full sheet cake. Bakeries bake the full sheet cake in one pan in a commercial size oven.
