### Pump flow calculation

Date: November 8, 2015 popularity: 272
Pump flow definition: flow refers to the volume (volume or weight) of the medium that the pump can pump and discharge in an hour
a. The volume flow (usually used flow) is expressed in Q, and the units are: m3 / S (cubic meter per second), m3 / h (cubic meter per hour), L / S (liter per second), etc
The volume flow rate has nothing to do with the properties of the liquid being transported
Unit conversion: L / S = 3.6 m 3 / h, 1 m 3 / h = 1 / 1000 m 3 / 3 600 s
1 cubic meter = 1000000 cubic centimeter, 1 hour = 3600 seconds
1 cm3 / S = 10 to the - 6th cubic meter / (1 / 3600 hours)
= 3.6 × 10 - cubic meter / hour
= 0.0036 m3 / h
Therefore, according to the above conversion formula, if the parameter of the product is 100 cubic centimeters per second,
The result of conversion is: 100 × 0.0036 = 0.36 m3 / h.
And so on!
b. Mass (weight) flow is expressed in QM in t / h (ton per hour), kg / S (kilogram per second), etc
The relationship between mass flow rate and volume flow rate is QM = q × P
Where p is the density of liquid (kg / M 3;, t / M 3;), and normal temperature water P = 1000 kg / M 3.
For example, if the flow rate of a certain pump is 50m3 / h, the weight of pumping per hour can be calculated?
The specific gravity of water is p = 1000kg / m3;
Solution: QM = QP = 50m? / h × 1000kg / M?; = 50000kg / h = 50t / h
That is to say, for normal temperature water, 1m 3 / h = 1t / h
