The use of test data in system design
The application and use of test data is probably the most common method of designing a pneumatic conveying system. This is used extensively in cases where test data or pre- vious experience with a material is available. Where no previous experience with a particular material is available, it is usual to obtain test data specifically for the purpose of system design, since the use of mathematical models is particularly unreliable in these situations. As for the section on the use of equations in system design, two logic dia- grams are also presented here, one for the original design of a system, and another for evaluating the capability of an existing system.
