# Pump And Formula for calculations - Need Help Please

• Eng_Luqman
In summary, the conversation discusses the process of calculating the pump and hydraulic system for a mechanical system. The pump pressure can be obtained from the pump curve and flow rate, while the required head or pressure is dependent on the system and flow rate. It is important to understand the piping system and its capabilities in terms of head loss in order to select the appropriate pump. Websites such as www.xs4all.nl/%7Ekostermw/dP/, www.mcnallyinstitute.com, and www.pumpworld.com provide resources for calculating pressure drop and learning more about pumps. For more specific information, www.lightmypump.com offers tutorials and calculator applets.

This is the diagram of the mechanical system that i want to calculate the pump and the full Hydraulic system for it ... calculating of pressure and the pump pressure and the electriacal motore for the that H. Pump for holding the coil

You will get the pump pressure from the pump curve and knowing the flow. If you are looking for required head or pressure, then it will totally depend on the system and the required flow.

You have to start with your system. You have to know what your piping system will provide in terms of head loss. Your piping and flow rate will dictate the pump selection. Pumps do not produce pressure, they produce flow. Your piping system creates the pressure as a result of resistance to the flow.

## 1. What is a pump and how does it work for calculations?

A pump is a mechanical device used to move fluids, such as liquids and gases, from one place to another. In calculations, pumps are used to determine the flow rate, pressure, and power required for a specific system.

## 2. What are the different types of pumps used in calculations?

There are several types of pumps used for calculations, including centrifugal pumps, positive displacement pumps, and reciprocating pumps. Each type has its own specific function and is selected based on the system requirements.

## 3. How do I calculate the pump flow rate?

The pump flow rate can be calculated by dividing the volume of fluid moved by the time it takes to move it. This can also be represented as the pump's discharge rate, which is typically measured in gallons per minute (GPM) or liters per minute (LPM).

## 4. What is the formula for calculating pump head?

The pump head is the measure of the energy required by the pump to move fluid against resistance. The formula for calculating pump head is: Head = (flow rate x pressure)/ (density x gravity). This formula takes into account the fluid's density, the acceleration due to gravity, and the pressure required to move the fluid.

## 5. How do I determine the power required for a pump?

The power required for a pump can be calculated by multiplying the pump head by the flow rate and dividing the result by the efficiency of the pump. This will give you the power required in units of watts (W) or horsepower (HP).
