Device and method for measuring exhaust area of turbine guider

The invention provides turbine guider exhaust area measuring equipment and a measuring method, the turbine guider exhaust area measuring equipment comprises an experiment assembly used for bearing a turbine guider, a water storage assembly arranged on the experiment assembly, and a clamping assembly connected with one side, facing the experiment assembly, of the water storage assembly, and one side, far away from the water storage assembly, of the clamping assembly sleeves the outer surface of the turbine guider. The water storage assembly is communicated with the turbine guider through the clamping assembly, and is used for taking standard measurement data of the standard turbine guider as reference data, and the reference data comprises standard exhaust area and standard water flow drainage time; the water storage assembly, the experiment assembly and the clamping assembly are used for measuring the time required for water to pass through the measured turbine guider at the same flow as the standard turbine
