Explain each of the following terms used in pumps: i) strainer; ii) static sunction lift; iii) volumetric flow.(6 marks)June/July 2020

i) A strainer is a device that is used to filter out any solid particles that may be present in a fluid. It is typically used in pump systems to protect the pump from damage caused by debris.

ii) Static suction lift refers to the maximum height that a pump can lift a liquid without any additional pressure being applied. This is determined by the density of the liquid and the atmospheric pressure.

iii) Volumetric flow is a measure of the volume of a fluid that is flowing through a pump in a given time period. It is typically measured in units of volume per time, such as liters per minute or gallons per hour. Volumetric flow is important because it determines the capacity of a pump and how much fluid it can handle.
