Tank filled with liquid, help?

In summary, to calculate the volume of liquid in a tank, measure its length, width, and height and use the formula Volume = Length x Width x Height. To determine the type of liquid, perform tests such as observing its color, smell, and density, or use a refractometer or pH meter. The maximum weight the tank can hold depends on its size and material, and can be determined by referring to the manufacturer's specifications or using a weight scale. To safely drain the liquid, use a siphon or pump and wear protective gear. If the liquid is hazardous, consult the MSDS and seek professional help for proper disposal.

Homework Statement


A tank is filled to the depth h1 with a liquid with mass density p Over the liquid surface is an atmospheric pressure po. From the bottom of the tank there`s a tube with cross-sectional area of ​​S. Tube expands to double cross-sectional area 2S while bending up to the height h4. Out of the pipe the fluid flows with velocity v.

Find the pressure in 1, 2, 3 and 4

1. How do I calculate the volume of liquid in a tank?

To calculate the volume of liquid in a tank, you will need to measure the length, width, and height of the tank in either inches, feet, or meters. Then, use the formula Volume = Length x Width x Height to determine the total volume in cubic units.

2. How do I determine the type of liquid in the tank?

To determine the type of liquid in the tank, you can perform a few simple tests such as observing the color, smell, and density of the liquid. You can also use a refractometer or pH meter to measure the properties of the liquid and compare them to known substances.

3. What is the maximum weight the tank can hold?

The maximum weight a tank can hold depends on the size and material of the tank. You can refer to the manufacturer's specifications or use a weight scale to measure the weight of the tank when it is filled with liquid to determine the maximum weight capacity.

4. How do I safely drain the liquid from the tank?

To safely drain the liquid from the tank, you can use a siphon or pump to transfer the liquid into a separate container. Make sure to wear protective gear and carefully follow the instructions for the siphon or pump to avoid any spills or accidents.

5. What should I do if the liquid in the tank is hazardous?

If the liquid in the tank is hazardous, it is important to handle it with extreme caution. You should consult the Material Safety Data Sheet (MSDS) for the specific liquid to understand its properties and potential risks. It is also recommended to seek professional help or contact your local hazardous waste management facility for proper disposal of the liquid.
