Calculating Pressure Drop

The basic formula for pressure drop (GRIP) os:

1f 1f; FLT: 0 133; Abo3; SyonP = K × (× v ² / 2) 1f; FLT: 1: 3; Aver3;

Dimana:

  • S01; ASA1; FLT: 0 AF3; K = 1; FLT: 1 1f 3; = Lost coefisien specient to the device
  • 1f 1f; 1f; FLT: 0 133; Abo3; lever1; FLT: 1 Aver3; = Fluid density
  • S01; S01; FLT: 0 AF3; VAL3; v ON1; FLT: 1 ASA3; = Velocity fluid

Kalkulate velocity (v) using flow rate (Q) and cross- sectionala area (A):

1f 1f; FLT: 0 133; Abo3; v = Q / A 1f; FLT: 1 123; 123;

Insert the velocity into te pressure drop formula to decie grese. Use producturer data for K and fluid atuties for reciachy.
