Volume flow rate (Q), specifies the volume of fluid flowing through the pump per unit time. Thus, it gives the rate at which fluid travels through the pump. Given the density of the operating fluid, mass flow rate (ṁ) can also be used to obtain the volume flow rate. The relationship between the mass flow rate and volume flow rate (also known ...
The flow rate is an important parameter for a pump. The flow rate in a peristaltic pump is determined by many factors, such as: Tube inner diameter – higher flow rate with larger inner diameter. Pump-head outer diameter – higher flow rate with larger outer diameter. Pump-head rotational speed – higher flow rate with higher speed.
Many liquid soap dispensers operate in this way as well. A few dispensers operate with a lever that pulls forward and squeezes the soap out. The majority of manual foam soap dispensers have the soap in a bladder in the dispenser in liquid form, as the pump is pressed the liquid soap is pushed through a small foaming nozzle which foams the soap.
Rate of flow may refer to: Mass flow rate, the movement of mass per time; Volumetric flow rate, the volume of a fluid which passes through a given surface per unit of ...
Refillable bottle with pump dispenser for liquid soap. A pump dispenser is used on containers of liquids to help dispensing. They might be used on bottles, jars, or tubes. Often the contents are viscous liquids such as creams and lotions. [1] Some are metered to provide uniform usage.
Specific Pump Power (SPP) is a metric in fluid dynamics that quantifies the energy-efficiency of pump systems. It is a measure of the electric power that is needed to operate a pump (or collection of pumps), relative to the volume flow rate. It is not constant for a given pump, but changes with both flow rate and pump pressure.
A metering pump moves a precise volume of liquid in a specified time period providing an accurate volumetric flow rate. [1] Delivery of fluids in precise adjustable flow rates is sometimes called metering. The term "metering pump" is based on the application or use rather than the exact kind of pump used, although a couple types of pumps are ...
In fluid dynamics, pipe network analysis is the analysis of the fluid flow through a hydraulics network, containing several or many interconnected branches. The aim is to determine the flow rates and pressure drops in the individual sections of the network. This is a common problem in hydraulic design.
