Patent abstract
A method for measuring average velocity pressure of a stack comprises the following steps. First, a total pressure measuring device is provided. The total pressure measuring device then measures the total pressure at a first location in the stack. Next, physical parameters comprising a distance between the first location and an outlet of the stack, a diameter and shape thereof are obtained. A formula of a static pressure and the average velocity pressure between the outlet and the first location is obtained by comparing the physical parameters to known fluid mechanics data. Finally, the average velocity pressure is obtained from the formula and the total pressure.
