TaskIt is convenient if you have instruments that can easily measure vital capacity in hot springs or swimming pools.SOLUTION:Provide a handle on the float and measure the load applied between the handle and the float.The difference between the loads on both sides of the handle between the handle and the float, which is obtained by squeezing the human body up to the neck in the water, with the state of the lungs exhausted and the condition of sucking in the air, is obtained, and the difference between the loads Calculate vital capacity from the corresponding volume and display it. Depending on the type and temperature of seawater and hot springs, correction is made depending on the difference in specific gravity.(FIG.
