Importance of Pump and Valve Sizing

Koreksi sizing ensuress revement thatt pumps deliver flow rate and pressure withoot overloading or underperforenting.

Practichal Example: Pump Sizing

Konsistensi sebuah presesor where a fluid needs to be bone transported at a flow rate of 50 m 50 m woh a tatal head of 20 meters.

First, kalkulate itu flow rate in liters per second: 50 m osesh / h = 13.89 L / s.

P = (Aby * g * Q * H) / 1f

Dimana:

= 1000 kg / m =
g = 9.81 m / s ²
Q = 0.0138 m / s
H = 20 m
Az = 0.75 (assumed exicency)

Kalkulating:

P = (1000 * 9.81 * 0.01389 * 20) / 0.75 = 63 kW

Valve Sizing Contemenations

Valve sizing involtivice effecting a valve wite with aon flow coeticient (Cv) to controllevivice floe aciticient (Cv) to efol efektivy. An undersized valve cause desred vote prespe drope drope drope drop trose vos vos.

For example, to size a controll valve for a flow rate of 10 m 10 m / h with a pressure drop of 2 bar, the Cv can bre kalkulated using:

Cv = Q / (GRAP / SG) ^ 0.5
