Lab Bernoulli

The document reports on tests of a tapered duct system at two positions. In test position 1, the duct tapers from 14° to 21° and flow rate, velocity, static head, dynamic head and total head are measured at six locations along the duct. In test position 2, the duct tapers from 21° to 14° but no data is reported. Graphs show the relationship between distance in the duct and measured head values for three tests in position 1.
