Water Discharge Volume in Usage Example
(Varies depending on steam pressure)
| Nominal Diameter | Steam Pressure (MPa) | ||
|---|---|---|---|
| 0.2 | 0.3 | 0.4 | |
| 15 | 3.2 | 4.1 | 4.8 |
| 20 | 4.7 | 5.4 | 6.0 |
| 25 | 6.1 | 7.1 | 7.5 |
| 32 | 8.8 | 10.5 | 11.6 |
Note: As the discharge height increases, the water discharge volume decreases.
Apply the following multipliers to the values in the above table:
At:
- 4 m discharge height: 80%
- 7 m discharge height: 70%
- 10 m discharge height: 50%
However, please refer to the table below for the maximum discharge height.
