The Cupola Heat Balance Using Programmable Calculator

In this paper, the cupola heat balance has been carried out by using programmable calculator with BASIC language. Computers tend to be used in almost every fields but for many people, computers are not handy yet because of its high equipment cost and its difficult language system. In view of this fact, a desk-top or a hand-held programmable calculator is the pertinent device in its calculation speed, accuracy, and easy programming language (BASIC), let alone its low cost. There have been some attempts to apply them to the foundry,${^{1),2)}}$ but they are little in number. This paper is the first attempt to apply the programmable calculator to the calculation of the cupola heat balance. After several applications in some practicalcases, the program has resulted in very satisfactory results such as saving of time and accuracy.
