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.
When we have family birthdays at our house I buy a 1/4 sheet cake. We usually have ten to twelve guests and it works fine. It all depends on how big the pieces you serve are. I cut mine in about 2 inch square pieces. I'd say 1/2 a sheet would feed between 20 and 24 people.Good luck./2 sheet is 16x24. It depends how tall the cake is, but if it's standard size, like 3 inches tall, then it can feed up to 50 people. Jazz Â· 10 years ago. Thumbs up.
