Centrifugal pumps are widely used in various industries for the transportation of fluids. Understanding the key formulas associated with centrifugal pumps is essential for designing and operating these pumps effectively. In this article, we will explore important formulas related to centrifugal pumps, including the calculation of fluid volume, velocity, Reynolds number, and more.
Volume of the fluid (Q ) Velocity of the Fluid ( V ) Here V = Velocity of fluid in m/sec Q =Volume of Fluid (m3/sec) A = Pipe line area (m2) V = Velocity of fluid in m/sec Q =Volume of Fluid in m3/hr A = Pipe line dia in mm ReynoldsNumberof the fluid HereD = Dia of the tube in meters V = fluid velocity in m/sec ρ=density
Volume of the Fluid (Q)
The volume of fluid flowing through a centrifugal pump can be calculated using the formula:
\[ Q = A \times V \]
Where:
- \( Q \) = Volume of fluid (m³/sec)
- \( A \) = Pipe line area (m²)
- \( V \) = Velocity of fluid in m/sec
Velocity of the Fluid (V)
The velocity of the fluid in a centrifugal pump can be determined by the formula:
\[ V = \frac{Q}{A} \]
Where:
- \( V \) = Velocity of fluid in m/sec
- \( Q \) = Volume of fluid in m³/hr
- \( A \) = Pipe line diameter in mm
Reynolds Number of the Fluid
The Reynolds number of the fluid flowing through a centrifugal pump can be calculated using the formula:
\[ Re = \frac{D \times V \times \rho}{\mu} \]
Where:
- \( Re \) = Reynolds number
- \( D \) = Diameter of the tube in meters
- \( V \) = Fluid velocity in m/sec
- \( \rho \) = Density of the fluid
- \( \mu \) = Viscosity of the fluid
Hydraulic Pump Power The ideal hydraulic power to drive a pump depends on liquid density , differential height to lift the material and flow rate of the material. Here 1. Hydraulic power in
The Affinity Laws of centrifugal pumps or fans indicates the influence on volume capacity, head (pressure) and/or power consumption of a pump or fan due to. change in speed of wheel - revolutions per minute (rpm); geometrically similarity - change in impeller diameter ; Note that there are two sets of affinity laws:. affinity laws for a specific centrifugal pump - to approximate .
