Читать книгу Introduction to Desalination - Louis Theodore - Страница 51

The amount of time it takes to check a problem is usually only a small fraction of the time it takes to solve it. Nearly all solutions to physical problems are amendable to verification. Thus, one should always:

1 Look for order-of-magnitude errors. Can the answer be checked by an approximate solution? Does the answer make sense?

2 Attempt to solve the problem by an alternate method.

3 Can the results be verified?
