How to determine the flow rate (steam, air)
First find the flow rate (W for steam, Q for air), the point of intersection of the pressure lines at inlet P1 and outlet P2. Then multiply the Q or W flow rate by the Cv factor for each model.
Example. • Model: DD-2-8 (Cv value: 0.55)
• Liquid: steam
• Inlet pressure (P1): 0.8 MPa
• Outlet pressure (P2): 0.5 MPa
The flow rate W is 92 kg / h, which corresponds to the intersection point P 1 = 0.8 MPa and P2 = 0.5 MPa, as shown by the dashed line.
Then multiply W = 92 kg / h by a Cv factor of 0.55. Thus: 92 kg / h x 0.55 = 50.6 kg / h
For water (Cv = 1)
How to determine the flow rate (water)
First find the differential pressure ∆P, then find the flow rate V using the diagram above. Then multiply the flow rate V by the Cv factor for each model.
Example. • Model: DD-3 (Cv value: 1.7)
• Inlet pressure (P1): 0.15 MPa
• Outlet pressure (P2): 0.05 MPa
Differential pressure: ∆P = P1 - P2 = 0.1 MPa. Then find the flow rate V = 14 l / min shown by the dotted line in the diagram. Then multiply V = 14 L / min by a Cv factor of 1.7. So: 14 l / min x 1.7 = 23.8 l / min
