New laws and mathematical formulas on hydrodynamics

The article is dedicated to the discovery of new laws of hydrodynamics defining moment of force, work, energy and time required to move one of the layer of water flow or liquid mixture flowing in the variable section of the river channel or pipe. According to the new laws of hydrodynamics and mathematical formulas, considering the total loss in the AC section or the horizontal tube, the mouth of the can to determine torque, work and energy of the liquid mixture passing through the variable section of the river or pipe. These laws are necessary in order to better understand the mechanism of movement of the fluid in the variable section of the river channel or pipeline, which often use Bernoulli's law, which is, as it were, a consequence of the law of conservation of energy. It should be noted that the law of Daniel Bernoulli does not meet the dimensional units of physical quantities and do not take into account a lot of losses in water flow or movement of the liquid mixture in the variable section of the pipeline, and even more so, the law can not determine the moment of force, work or energy of moving water flow the bed of the river.
