Calculation of pump mechanical loss power

2012-10-25 21:55 | Publisher: helloshigy | see: nineteen thousand and fifty-five | Comments: 0

abstract : Mechanical loss power includes three parts: wheel resistance loss power, friction loss power at shaft seal and friction loss power between shaft and bearing are calculated according to the formula Nm=Ndf+△ N2+△ N3
Calculation of pump mechanical loss power
Note: Please enter three of the four items and set the unit, then click the Calculate button to calculate the other item. The input must be a numeric value or a legal formula
Support scientific counting method input, for example, 3.14e-5.6 can be input to indicate 3.14 × 10 -5.6

Basis description
According to formula N m =N df +△N two +△N three Calculate
Where, N m ——Mechanical loss power, W; N df ——Wheel resistance loss power, W; △ N two ——Friction loss power at shaft seal, W; △ N three ——Friction loss power between shaft and bearing, W
Please enter the function in the following table format. Functions or expressions can be nested in the function
For example: 3.14 * pow (5 * lg (4 * 8), 4+8 * sin (30))
The unit of trigonometric function is degree
