| Hose style | Common wall range | Weight behavior | Calculator note |
|---|---|---|---|
| PVC garden hose | 0.08 to 0.14 in | Light empty weight, water dominates when full | Measure ID because nominal size can vary |
| Rubber contractor hose | 0.12 to 0.20 in | Heavier wall and better kink resistance | Wall estimate helps loaded handling weight |
| Layflat discharge hose | 0.04 to 0.10 in | Low wall volume, high fluid volume on large IDs | Use fill percent for partially drained sections |
| Hydraulic hose | 0.14 to 0.35 in | Reinforcement can outweigh the contained fluid | Select reinforced material for closer wall weight |
| Coolant or heater hose | 3 to 6 mm | Short runs but dense fluid mixes are common | Use glycol preset or custom kg/L density |
When you move liquid through an hose, you are moving weight. Empty hoses is light, but full hoses of liquid have moreer weight. The weight of the liquid in a hose change how you have to handle the hose and how many person are required to move that hose.
The weight of the hose are important in that the weight will determine if a structure can support the hose without it break. In order to calculate the weight of the liquid in a hose, you must understand the printed size of the hose. The size of the hose printed on the hose may not be the exact diameter of the inside of the hose.
How to Calculate the Weight of a Hose
To find the exact inside diameter of the hose, you can use calipers to measuring that value. The inside diameter of the hose will determine the volume of the liquid. As the inside diameter of the hose increases, the volume of the liquid increase, as well.
Thus, to calculate the weight of the hose, you must measure the inside diameter of the hose. Another factor that will change the total weight of the hose is the density of the liquid. Water is a common liquid for which hoses is used, but other liquids can also be used.
For instance, glycol, hydraulic oil, or diesel can be used in some case. Each of these liquids has a different density. For instance, diesel is more denser than water.
Additionally, the temperature of the liquid will change the density of the liquid, as well as the total weight of the hose. For instance, cold glycol is more denser than warm glycol. Thus, you must consider the density of the liquid in calculating the total weight of the hose.
Another variable that must be considered in calculating the total weight of the hose is the fill percentage of the hose. It is common for a hose to not be completely filled with liquid, there may be liquid left in the fitting of the hose, for instance. Thus, rather than assuming the hose is 100% filled, it is better to use a fill percentage for the calculation of total hose weight.
Using a percentage will allow for the total weight of the liquid in the hose to be more accurate calculated than if the percentage was assumed to be 100%. Another factor in the total weight of the hose is the weight of the wall of the hose. For instance, a heavy hose will have more weight then a hose with a thin wall.
Thus, in addition to the weight of the liquid in the hose, you must also consider the weight of the hose wall in calculating the total loaded weight of the hose. The length of the hose is another variable in calculating the total weight of the hoses. For instance, a single long hose will have a different weight than a number of short hoses.
This is due to the number of fittings on each hose. Thus, it is important to count every hose that is to be used. The outside diameter of the hose is one more variable that should be considered.
The outside diameter of the hose will determine the size of the reel on which the hose is to be stored. The thickness of the wall of the hose will affect the outside diameter of the hose. Thus, you must also consider the outside diameter of the hose in calculating the total weight of the system of hoses.
In calculating the total weight of the hoses, it is recommended to use a conservative percentage of the total fill of the hoses. By using a conservative percentage, the total weight will account for any air pocket that may be in the hose or for the fact that the hose may not be completely filled with liquid when it is first used. One of the major reasons that it is important to calculate the total weight of the hose is for safety.
Very heavy hoses can be difficult to move. Furthermore, if the hose is too stiff it can also cause injuries to the person that move the hose. Additionally, you should also consider the pressure rating of the hose and the condition of the fittings in ensuring the safety of those using the hose.
Thus, knowing the weight of the hose is another factor in the safety of the person using that hose. To calculate the total loaded weight of a hose, follow the following steps. First, determine the inside diameter of the hose.
Second, determine the density of the liquid. Third, calculate the percentage of the hose that is to be filled with the liquid. Finally, add the weight of the wall of the hose to the weight of the liquid that is calculate with the third step.
By following these steps, the hose weight calculator will calculate the total loaded weight of the hose for you.
