Novel fluid mechanics comprehensive experiment device

The utility model relates to a teaching apparatus, in particular to a novel fluid mechanics comprehensive experiment device, which is characterized in that an experiment tube comprises an experiment tube A and an experiment tube B, wherein both ends of the experiment tube B are respectively communicated with a constant pressure water tank and an auxiliary water tank, the experiment tube B is provided with a pressure measuring tube in a communicating manner, and the experiment tube B is further provided with a pitot tube and an increasing coupling; the experiment tube A is an isometric horizontal straight tube, both ends of the experiment tube A are respectively communicated with the constant pressure water tank and the auxiliary water tank, a joint of the experiment tube A and the constant pressure water tank is provided with a color water introduction tube, and the color water introduction tube is communicated with a color water container through a color water fine adjuster and a regulating valve. According to the utility model, one machine has multiple purposes so as to finish a reynolds experiment, an incompressible fluid constant flow grossflow bernoulli equation experiment, a pitot tube flow speed measurement experiment, a frictional drag coefficient measurement experiment and a local resistance coefficient measurement experiment, and a fluid flow condition and relative knowledge points are really completely shown to an experiment operator.
