This book is a textbook compiled for experiments in hydraulics, engineering fluid mechanics, fluid mechanics and other courses. The book is divided into two chapters, including 10 demonstration experiments and 11 operational experiments. The experimental content covers hydrostatics, basic principles of fluid motion, constant total flow continuity equation, energy equation and momentum equation, different flow patterns and head loss rules, head loss along the way and local head loss rules, orifice outflow and nozzle outflow, siphon flow, water pump flow, cavitation erosion, open channel water surface curve, weir gate flow, hydraulic jump phenomenon, seepage flow network, and demonstration of modern measurement technology. This book can be used as a textbook for water conservancy, civil engineering, environment, machinery and other science and engineering majors in colleges and universities, and can also be used as a reference book for teachers in related majors.
