This calculation tool allows you to calculate the power absorbed by a pump knowing the characteristics of the pipe and the fluid, the pressures and the pressure drop. The values ​​of some parameters such as the efficiency of the pump, the density of the liquid and the roughness of the pipe are already suggested as they are very common, but obviously they can be modified in case of different operating conditions.

Flow Rate Calculation Based on the Size of the Valve Based on the operating conditions of the process, this tool allows you to calculate the flow rate of the fluid that can flow inside the valve in use. By entering the selected valve type, the inlet and outlet pressure and the fluid properties as input, the tool displays the characteristic curve diagram. In this way it is possible to identify the flow range in which operation is recommended, depending on the degree of opening of the valve. In order to achieve optimal regulation, it is recommended to size the valve so that the flow remains in the middle of the curves.

With this calculation tool you can calculate the total pressure losses within a system, i. H. distributed and local pressure drops. Distributed pressure drops occur when the energy loss is generated by the surface friction developed between the fluid and the tube walls. In the case of point leaks, on the other hand, the energy loss is generated by form friction, due to a change in direction of the fluid in the presence of valves or fittings.

Tools for installation

Due to temperature changes in a system, pipes can expand and contract. To prevent breakage of the fasteners, compensators are usually used or expansion rings or direction changes are made. This tool allows us to calculate the correct parameters to prevent the potential expansion or contraction of our systems.
