Validation
The coefficient of discharge (Cd) is calculated as follows:
|
11.2 |
where,
| A | Area of Orifice(m2): 5.02655E-05 |
| m. | Outlet Mass Flow Rate (kg/s): 0.68 |
|
Density (kg/m3): 1000 |
| P1 | Inlet Pressure Pa: 250000 |
| P2 | Outlet Pressure Pa: 95000 |
The comparison of the coefficient of discharge from experiments and Simerics-MP+ are as follows:
| Experiment | Simerics MP+ | |
|---|---|---|
| Coefficient of discharge | 0.78 | 0.768 |
