Basis description

According to the formula

Speed flow ratio law calculation formula

Calculate

Where, Q_one ——Flow 1, m^three /s； Q_two ——Flow 2, m^three /s； n_one ——Speed 1, rpm; n_two ——Speed 2, rpm
Note: It is applicable to the condition that the conveying medium remains unchanged. At this time, the geometric dimension scale constant λ L=1

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
