Reward-based calculation, assessment of the benefits of pipeline drag reducers
Thread Content
Gentlemen, it is known that a certain pipeline drag reducer can reduce the resistance of circulating water by 40%. How can the benefits resulting from this be calculated? Thank you
Recalculate the pipeline losses and select a new pump; the efficiency of the pump increases while its head decreases. The shaft power before and after calculation is then divided by the efficiency of the motor (the transmission efficiency of the coupling is ignored) to determine the input power of the motor before and after. The difference represents the power saved; multiplying this by the number of hours gives the amount of electricity in kilowatt-hours
