Hello everyone,
i am mechanical design engineer and i want to find lobe pump fluid slippage by empirical formula?
can anyone help me?

my input data are as below:

Pump:Lobe pump
Rotor Type: tri-lobe
P1= -0.03 bar (suction side/input side)
P2= 3.5 bar (discharge side/output)
Q= 60.00 Ltr/min
RPM: 279 RPM
viscocity of fluid (dynemic) = 1 C.Poise (for water)

sleep area Detail :
width of clearance(B)=34.70 mm
height of clearance(t)= 0.20 mm
length of Clarence (L)= 9.75 mm

from the above data find out leakage fluid qty. by equation?

Thanks in advance.

Best Regards,
