Power Loss due to Shafting :
- The power produced at the shaft, known as Shaft Power, is therefore reduced.
- To put some approximate numbers to these losses, the most efficient 4‐stroke engines can be expected to show about 12.5% loss, and usually the loss is worse than that.
- The pump shaft power is also called the absorbed power.
- It is the power that needs to be actually applied at the coupling / shaft to get the considered flow and head.
- It includes some losses and is therefore higher than the hydraulic power.
- The pump shaft transmits the drivetorque to the impellers to centrifugal pumps or to the displacement elements of rotary positive displacement pumps.
- The formula for the calculation is given below.
- Power Loss due to Shafting = Unit Power Loss * Setting from Head Base to Top of Bowls.
- Beside the formula this calculator works.
How to Calculate ?
- First, Enter the Unit Power Loss. Then,
- Second, Enter the Setting from Head Base to Top of Bowls. Then,
- Click “Calculate” to get the result and then if you want to clear values Click “Reset” in addition to clear the values.
- Finally, follow these steps to get the result.
