BLOWER POWER CALCULATION FOR LOBE TYPE

Blower & pump  Size Calculations

BLOWER POWER (KW ) CALCULATORS FOR  LOBE TYPE 

The Hp/KW of blower can be calculated based on flow and head, the below calculator help of calculate the pump capacity specially of lobe and centrifugal blowers. Below Yellow Highlighted Data can be change by user and Green is output.

LOBE BLOWER POWER CALCUALTION
1	W0		Nm3/Hr
2	W		lbs/min	: flow in Nm3/hr x air density (Kg/m3)
3	Z		Com pressbility of air
4	T0		◦C
5	T		Temp in ◦ Rabsolute
6	M		Molecular weight of air
7	suction pressure		ATM
8	head required		Bar
9	Dischage Pressure		Bar.a
10	Rc

PUMP POWER CALCULATION OF CENRIFUGAL OR SUBMERSIBLE PUMP

Blower & pump  Size Calculations

PUMP POWER (KW/HP)  OF CENRIFUGAL OR SUBMERSIBLE PUMP 

The Hp/KW of Pump can be calculated based on flow and head, the below calculator help of calculate the pump capacity specially of submersible pumps and centrifugal pumps. Below Yellow Highlighted Data can be change by user and Green is output.

PUMP POWER CALCULATION
PUMP INPUT DATA
Particular	Value	Unit	Base Formula
Required Flow		m3/hr	BKW= flow x Head X SG/ (367 x eff.)
Required Head		mlc
SG of Liquid		(1 for water)
Efficiency of Pump		(fall between 0.5 to 0.9) depend upon desing and type
