Solving For Velocity at Point 1
Inputs:
Conversions:
| static head or elevation (Z1) | = | 0 | = | 0 | meter | |
| static head or elevation (Z2) | = | 0 | = | 0 | meter | |
| pressure (P1) | = | 0 | = | 0 | pascal | |
| pressure (P2) | = | 0 | = | 0 | pascal | |
| velocity (V2) | = | 0 | = | 0 | meter/second | |
| density (p) | = | 0 | = | 0 | kilogram/meter^3 | |
| acceleration of gravity (g) | = | 0 | = | 0 | meter/second^2 | |
| head loss (h) | = | 0 | = | 0 | meter |
Solution:
| velocity (V1) | = | HAS NOT BEEN CALCULATED |
