Power Loss due to Shafting
 Unit Power Loss (hp/ft) : Setting from Head Base to Top of Bowls (ft) : Result :
##### Definition :
• 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.
##### Uses :
• The pump shaft transmits the drivetorque to the impellers to centrifugal pumps or to the displacement elements of rotary positive displacement pumps.
##### Formula :
• 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.
